Full textAbstract:
The research focuses on the relationship and interlinking between the different architectural domains within the enterprise architecture of an enterprise. The architectural domains are grouped together as business architecture, information architecture and technology architecture.
First, a literature review of the definitions, history, role, functions and qualities, existing frameworks, models and domains of enterprise architecture was conducted. The definitions; role and benefits; models, frameworks, ontologies and descriptive languages of the different architectural domains were then studied as background and basis. New definitions were deduced.
Second, the modelling methodology, process, elements and deliverables were investigated. An integration metamodel for enterprise architecture was developed, according to this modelling methodology. The metamodel is called the Relational Enterprise Architecture Metamodel or the REAM.
Third, the research methodology for the empirical research section was investigated and determined. The proposed conceptual metamodel has been assessed through a case study within three different industries each. The feedback from the case studies was used to modify/enhance the metamodel. The possibilities for application of the modified model were then assessed at the University of Pretoria.
The contribution of this research lies mainly in the development, empirical testing and refining of an integrated EA metamodel (REAM) as well as the development of new definitions for enterprise, business, information and technology architecture and relating them.Thesis (PhD)--University of Pretoria 2015.

Full textAbstract:
Many scholarly tasks involve working with contextualized fine-grain information, such as a music professor creating a multimedia lecture on a musical style, while bringing together several snippets of compositions of that style. We refer to such contextualized parts of a larger unit of information (or whole documents), as subdocuments. Current approaches to work with subdocuments involve a mix of paper-based and digital techniques. With the increase in the volume and in the heterogeneity of information sources, the management, organization, access, retrieval, as well as reuse of subdocuments becomes challenging, leading to inefficient and ineffective task execution. A digital library (DL) facilitates management, access, retrieval, and use of collections of data and metadata through services. However, most DLs do not provide infrastructure or services to support working with subdocuments. Superimposed information (SI) refers to new information that is created to reference subdocuments in existing information resources. We combine this idea of SI with traditional DL services, to define and develop a DL with SI (an SI-DL). Our research questions are centered around one main question: how can we extend the notion of a DL to include SI, in order to support scholarly tasks that involve working with subdocuments? We pursued this question from a theoretical as well as a practical/user perspective. From a theoretical perspective, we developed a formal metamodel that precisely defines the components of an SI-DL, building upon related work in DLs, SI, annotations, and hypertext. From the practical/user perspective, we developed prototype superimposed applications and conducted user studies to explore the use of SI in scholarly tasks. We developed SuperIDR, a prototype SI-DL, which enables users to mark up subimages, annotate them, and retrieve information in multiple ways, including browsing, and text- and content-based image retrieval. We explored the use of subimages and evaluated the use of SuperIDR in fish species identification, a scholarly task that involves working with subimages. Findings from the user studies and other work in our research lead to theory- and experiment-based enhancements that can guide design of digital libraries with superimposed information.Ph. D.

Full textAbstract:
The need for change of direction in Software Engineering has been suggested in severalresources [Power of Models]. In recent years many organizations have focused on ModelDriven Engineering (MDE) as an approach to application design and implementation.Model Driven Architecture (MDA) was introduced by Object Management Group (OMG) in2001 in support of MDE. Models are the basic elements in MDE. The focus on MDE is onthe concept of “Everything is a model”. So far several languages, tools and platforms havebeen created for MDE.In particular, models can be developed in a distributed environment, thus once they mergetogether, conflicts and inconsistencies should be detected in a convenient way to bereconciled (automatically by software or manually by developers). This project is based onprevious works that define difference and conflict metamodels of a source model. In thisreport, we introduce the benefits of versioning systems in MDE framework. A conflictmetamodel that is generated from the input metamodel and the architecture for detectingconflicts are represented. The proposed approach is metamodel independent that meansconflict metalmodel is created for any input model which conforms to Kernel Meta MetaModel (KM3). The concept of used conflict model can be also changed regardless ofmodels. The extended idea for conflicts detection, the presented architecture for modelcode management and the tools that can detect conflicts of concurrent models can help toimprove MDE in model code management. For this report, some implementation in Eclipseplatform has been rendered while some future works are suggested.

Pastaruoju metu informacinių technologijų pasaulyje dažnai minimos paslaugomis ir įvykiais grindžiamų sistemų architektūros. Greitai besikeičiančiame verslo pasaulyje įmonėms yra aktualu turėti sistemas, kurios greitai ir lengvai būtų priderintos prie besikeičiančių verslo procesų ir sumažintų tokių sistemų kūrimo ir palaikymo išlaidas. Naudodamos paslaugomis grindžiamą architektūrą, įmonės gali lanksčiai tvarkyti savo veiklą ir kurti sistemas, nekeisdamos turimos techninės ar programinės įrangos. Nors literatūroje yra gausu straipsnių apie įvykiais grindžiamas sistemas ir jų privalumus, tačiau sistemos architektui, nusprendusiam sukurti įvykiais grindžiamos sistemos projektą, iškyla aktualus klausimas: kaip aprašyti ir modeliuoti įvykius, kurie ateina iš išorės arba sugeneruojami pačios sistemos ar vartotojų veiksmų su sistema metu. Akivaizdu, kad šiuo metu nėra populiarios metodikos, kuri apibrėžtų, kaip reikia atlikti įvykių modeliavimą ir jį panaudoti informacinių sistemų kūrimo procese. Šiame darbe nagrinėjami įvykiais grindžiamų sistemų modeliavimo metodai ir realizavimo technologijos. Atsižvelgiant į analizės rezultatus pateikiama įvykiais grindžiamų sistemų modeliavimo ir realizavimo metodika. Ši metodika pritaikyta ir įvertinta sukuriant publikacijų portalo prototipą.Nowadays the terms SOA (Service Oriented Architecture) and event driven systems are often used when talking about systems with large scalability, performance and interoperability. In fast changing business world it is vital to have systems that could be easily changed whenever new functionality is needed. Using service oriented architecture companies can easier adapt its business process to changed business rules. Even though there are a lot of articles and publications about event driven systems and their advantages, but the system architect who decides to build an event driven system is facing the problem: how to model and describe events of the system. Obviously, that there are no popular and widely accepted methodology for event driven system modelling. The goal of this work is to develop a methodology for modelling an event driven systems. This methodology describes the metamodel for event modelling and the usage of the event model in system development life cycle. The developed methodology for modelling and implementation of event-driven information systems was used for making a model of publications portal prototype. Usage of this methodology in system design process adds more clarity, because all the events, which can be generated in the system and their types, are described in one diagram – event model. The event model elements can be used in other model diagrams, such as sequence or state machine diagrams.

A construção de aplicações Web é algo complexo, pois envolve requisitos não previstos na modelagem de sistemas convencionais. O ambiente Web agrega características como: navegabilidade, estruturação de hiperdocumentos, workflow, acessibilidade, escalabilidade, usabilidade, compatibilidade, interoperabilidade, segurança, aspectos culturais, entre outros. O presente trabalho propõe que a modelagem de sistemas de informação na Internet incorpore características existentes na modelagem de sistemas de gerência de workflow manipulando hiperdocumentos. A notação utilizada é uma extensão à notação da UML (Unified Modeling Language). Esta consiste de novos estereótipos que modelem hiperdocumentos e sistemas de gerência de workflow em sistemas de informação na Web. A extensão propõe a utilização de diagrama de atividades estendido para modelar o workflow de atividades, o qual manipula hiperdocumentos envolvidos no domínio de uma aplicação Web. Os hiperdocumentos são modelados através de diagramas de estrutura de documentos, que são derivados do diagrama de classes da UML. A navegabilidade dos documentos é desenhada através dos diagramas de contexto de navegação e restrições de acessos de em casos de uso. Finalizando a modelagem, o diagrama de estrutura de documentos recebe todas as características dinâmicas, estáticas e de ligação que são modeladas através dos diagramas estendidos bem como pelos diagramas comportamentais e estáticos da UML. A modelagem segue a notação da UML, sendo sugerido que numa primeira etapa, modele-se os hiperdocumentos e sua estruturação preliminar. Na seqüência, com auxílio do diagrama de casos de uso, modela-se o fluxo de atividades através do diagrama de atividades estendido. Após este levantamento, tanto de documentos quanto de atividades envolvidas no domínio da aplicação, modela-se o contexto de navegação e restrições em acessos de casos de uso, que evidenciam os componentes de ligação necessários à navegabilidade entre os hiperdocumentos. Através da extensão proposta à notação da UML, que considera aspectos de workflow, estruturação de hiperdocumentos e navegabilidade, as fases de projeto e implementação de software, sofrem menos alterações e interferências de adaptação às características das ferramentas de implementação para este novo ambiente.Implementation of Web applications is a complex task since it involves requirements not previously accounted for modelling conventional systems. The Web environment possesses characteristics such as ease of navigation, hyperdocument structuring, workflow, access and scale facilities, usability, compatibility and interoperability, safety and cultural aspects amongst others. The present work proposes that modelling of information systems in the Internet incorporate the existing characteristics of modelling workflow management systems to handle structured hyperdocuments. The notation used is an extension to the UML (Unified Modelling Language) notation, which consists in new stereotypes for hyperdocument modelling and incorporated workflow in information systems. The extension proposes use of the extended diagram of activities to model the activity workflow which will handle the hyperdocuments involved in the domain of a Web application. The hyperdocuments will be modelled using diagrams of document structure, which are derived from the UML class diagrams. The navigation of documents is designed using the surfing context diagrams and access restriction associated to the use cases. Modelling is finalised by adding to the document structure all the dynamic, static and link characteristics which are modelled though the extended diagrams, as far as the behaviour and static diagrams of the UML. The modelling procedure follows the UML notation, being suggested that, in a first step, the modelling of a preliminary document structuring. In sequence, using the diagram of use cases, the activity flow is modelled by using the extended diagram of activities. After the research procedures associated to documents and activities related to the application domain, the surfing contexts and access restrictions of the use cases are modelled to evince the link components necessary to the navigation amongst documents. The use of the proposed extension to the UML notation, which accounts for workflow aspects, hyperdocument structuring and its navigation, will lead to less changes of the project development and software implementation to account for the characteristics of the implementation tools for this new environment.

Pastaruoju metu šio mokslo vystymosi eigoje formuojasi naujas etapas – žiniomis grindžiama kompiuterizuota IS inžinerija. IS kūrimo aplinka CASE yra papildoma veiklos žinių kaupimo posistemiu, intelektualizuojančiu informacijos sistemos kūrimo procesą. Veiklos žinių posistemio paskirtis teoriškai yra užtikrinti galimybę saugomų dalykinės srities žinių pagrindu generuoti IS konceptualaus ir detalaus projektavimo etapų modelius ir programinį kodą. Veiklos modelio panaudojimas gerina sprendimų kokybę ir taupomas darbo laikas, kadangi veiklos modelyje jau yra sukauptos formalių kriterijų atžvilgiu patikrintos žinios. Priešingai negu tradicinėje kompiuterizuotoje IS inžinerijoje, kur informacijos sistema kuriama empiriškai, pradedant vartotojo poreikių išsiaiškinimu, analize ir specifikavimu.

Full textAbstract:
Hadron Therapy (HT) exploits properties of ion radiation to gain therapeutic advantages over existing photon-based forms of external radiation therapy. However, its relative superiority and cost-effectiveness have not been proven for all clinical situations. Establishing a robust evidence base for the development of best treatment practices is one of the major challenges for the field. This thesis investigates two research infrastructures for building this essential evidence. First, the thesis develops main components of a metadata-driven software architecture for the collection of clinical information and its analysis. This architecture acknowledges the diversity in the domain and supports data interoperability by sharing information models. Their compliance to common metamodels guarantees that primary data and analysis results can be interpreted outside of the immediate production context. This is a fundamental necessity for all aspects of the evidence creation process. A metamodel of data capture forms is developed with unique properties to support data collection and documentation in this architecture. The architecture's potential to support complex analysis processes is demonstrated with the help of a novel metamodel for Markov model based simulations, as used for the synthesis of evidence in health-economic assessments. The application of both metamodels is illustrated on the example of HT. Since the biological effect of particle radiation is a major source of uncertainty in HT, in its second part, this thesis undertakes first investigations towards a new research facility for bio-medical experiments with ion beams. It examines the feasibility of upgrading LEIR, an existing accelerator at the European Organisation for Nuclear Research (CERN), with a new slow extraction and investigates transport of the extracted beam to future experiments. Possible configurations for the slow-resonant extraction process are identified, and designs for horizontal and vertical beam transport lines developed. The results of these studies indicate future research directions towards a new ion beam facility for biomedical research.

Full textAbstract:
In this paper, the method is proposed for transforming UML class diagrams with OCL constraints to relational database schemas, having advantages over “UML Profile for Databases” models. The proposed method consists of two phases supplementing each other: metamodel based transformations and pattern-based transformations. All transformations are based on OMG official standards or RFPs (Request for Proposals) and are prepared for use in MDA (Model Driven Architecture) context. This means, that resulting models, created using the described method, are long-lasting, independent from platform and abstract enough to be independent from technology.
This work covers analysis of the field of object – relational transformations, analysis of support of OCL in currently used UML tools, transformation rule sets of metamodel transformations and pattern-based transformations, a lot of examples illustrating every transformation. Metamodel transformations are designed to transform object models written in UML language to corresponding relational models: types, classes, attributes, association classes, associations to tables, columns, foreign keys and other concepts. Pattern-based transformations are designed for generating static relational concepts such as check constraints, views, stored procedures and triggers. Using the two described transformation types and the whole method described, one can generate full-fledged relational database schemas, have precise UML models and keep much more... [to full text]

The aim of this project is to create a metamodel from a drilling tool with replaceable inserts from FEA of the machining process using MATLAB and ABAQUS. This report contains research in drilling and in metamodeling using neural networks and the work from the design of the CAD, through FEA and simulations, to the metamodeling, excluding the optimization. The work has resulted in a framework where a base FE model of the drill with two inserts that works, but due to time issues and given high cutting speed and feed the results of the FEA and the metamodeling are not very accurate. Therefore, the optimization analysis could not be done. However, it has been shown that feed has a major influence on the inserts temperature than the cutting speed, despite the higher range of this last one.

Full textAbstract:
This research identifies a current and future need in the realm of information systems development which has surfaced as a result of layered architectures and software reuse. An analysis methodology based upon two three-dimensional metamodels which correspond to the principal aspects of system architecture, structure and communication, is developed. Each metamodel can be viewed as having three planes which represent increasing abstractions away from actual source code. For example, with regard to the structure metamodel, the lowest plane corresponds to actual source code structures written in a specific computer language, the middle plane represents the general form of the structure available in that language, and the top plane represents the general form of structures available in any language. An object-oriented viewpoint was adopted in order to allow the expression of the relationships between entities found on a single plane of a metamodel, as well as the expression of the relationships between entities found on different planes. The metamodels provide a framework and methodology for discerning the structure and communication mechanisms employed in software source code as well as a framework from within which behavioral models can be developed.

Conselho Nacional de Desenvolvimento Científico e TecnológicoThe interpretation and understanding of large quantities of data is a challenge for current information visualization methods. The visualization of information is important as it makes the appropriate acquisition of the information through the visualization possible. The choice of the most appropriate information visualization method before commencing with the resolution of a given visual problem is primordial to obtaining an efficient solution. This article has as its objective to describe an information visualization classification approach based on Treemap, which is able to identify the best information visualization model for a given problem. The implementation of the model involves choosing components and also the architecture that stands its necessary functions effectively. This is understood through the construction of an adequate information visualization meta-model. Firstly, the actual state of the visualization field is described, and then the rules and criteria used in our research are shown, with the aim of presenting a meta-model proposal based on treemap visualization methods. Besides this, the author present a case study with the information contained in the periodic table visualization meta-model along with an analysis of the information search time complexity in each of the two meta-models. Finally, an evaluation of the results is presented through the experiments conducted with users and a comparative analysis of the methods based on Treemap and the Periodic Table.

Full textAbstract:
BACKGROUND: Descriptions of data, metadata, provide researchers with the contextual information they need to achieve research goals. Metadata enable data discovery, sharing and reuse, and are fundamental to managing data across the research data lifecycle. However, challenges associated with data discoverability negatively impact on the extent to which these data are known by the wider research community. This, when combined with a lack of quality assessment frameworks and limited awareness of the implications associated with poor quality metadata, are hampering the way in which epidemiological and public health research data are documented and repurposed. Furthermore, the absence of enduring metadata management models to capture consent for record linkage metadata in longitudinal studies can hinder researchers from establishing standardised descriptions of consent. AIM: To examine how metadata management models can be applied to ameliorate the use of research data within the context of epidemiological and public health research. METHODS: A combination of systematic literature reviews, online surveys and qualitative data analyses were used to investigate the current state of the art, identify current perceived challenges and inform creation and evaluation of the models. RESULTS: There are three components to this thesis: a) enhancing data discoverability; b) improving metadata quality assessment; and c) improving the capture of consent for record linkage metadata. First, three models were examined to enhance research data discoverability: data publications, linked data on the World Wide Web and development of an online public health portal. Second, a novel framework to assess epidemiological and public health metadata quality framework was created and evaluated. Third, a novel metadata management model to improve capture of consent for record linkage metadata was created and evaluated. CONCLUSIONS: Findings from these studies have contributed to a set of recommendations for change in research data management policy and practice to enhance stakeholders’ research environment.

Full textAbstract:
Metamodellierung im Sinne der Meta Object Facility (MOF) stellt eine Methode für die strukturelle Definition der abstrakten Syntax von Modellierungssprachen und Modellen im Softwareentwicklungsprozess dar. Um Modellsimulation und dynamische Analysen für metamodellbasierte Sprachen zu unterstützen, fehlt es an einem Kalkül zur operationalen Semantik. In dieser Arbeit wird ausgehend von MOF die Aktionssemantik MActions entwickelt, die die Definition von operationaler Semantik als Verhalten in Metamodellen ermöglicht. Diese Erweiterung geht einher mit der Beschreibung von Laufzeitmodellen sowie Zuständen und Parallelitätseigenschaften, so dass eine Verifikation von dynamischen Eigenschaften möglich wird. Zu diesem Zweck wird mit der Linear Temporal Object Constraint Language (LT-OCL) exemplarisch eine prädikatenlogische Temporallogik entwickelt, die eine metamodellunabhängige Analyse für ausführbare Modelle erlaubt. Dabei ist die Semantik von temporalen Ausdrücken über Zuständsänderungen von (aufgezeichneten) Ausführungsläufen beschrieben, wobei eine Linearisierung parallele Änderungen zusammenführt. Als weiteren Anwendungsfall der dynamischen Analyse untersuchen wir die Relation zum Verhaltensvergleich im Sinne der Bisimulationstheorie. Metamodelle, Aktionssemantik und Temporallogik werden mittels einer erweiterten Abstract State Machine (ASM) formal beschrieben und kommen in zwei Fallstudien zur Anwendung (Timed Automata und C#).Object-oriented metamodelling as defined by the Meta Object Facility (MOF) provide a means to describe the structure of models and the abstract syntax of modelling languages at various stages in a software development process. However, MOF lacks concepts for the definition of operational semantics and there is no support for dynamic model analysis based on the semantics and abstract states of a language definition. This thesis investigates on extending the metamodelling framework with an action semantics - the MActions - to support the definition of operational semantics in metamodels and enable simulation as well as verification of dynamic properties. For this purpose, runtime models are incorporated with semantics for states, time, and properties of parallelism that allow a generic analysis solely bound to a certain metamodel definition. Furthermore, we develop the Linear Temporal Object Constraint Language (LT-OCL) to perform a dynamic analysis of execution runs based on the executable models. The semantics of this temporal predicate logic is bound to state changes of (recorded) execution traces that are linearizations of parallel changes of the runtimes model. This establishes the link to the theory of bisimulation as a second application case of dynamic analysis. Abstract State Machines (ASM) have been used to formally define the action language in conjunction with metamodels and the temporal logic. As proof of concept of the whole approach, the framework has been implemented and applied to two languages as case studies (namely Timed Automata and C#).

Quality has always been an elusive concept in information system design, even more so when dealing with the online-sphere. The purpose of this thesis is to investigate and dissect the concept of quality and present a practical way to apply it to the design process. To do this, a quality-driven design model has been developed, focused around four crucial aspects of overall quality: accessibility, usability, navigation and interactivity. By utilizing simple and practical techniques and measuring their success in achieving quality, this study attempts to prove that quality can be harnessed as a hands-on resource, guaranteed in any design project involving a Web-Based Information System, merely by applying this model.
Kvalitet har alltid varit ett begrepp svårt att fånga och tillämpa, speciellt när området Internet kommer in i bilden. Den här C-uppsatsen har således som syfte att undersöka och bryta ned kvalitetskonceptet samt presentera ett praktiskt tillvägagångsätt som kan utnyttjas under design processen. För att göra detta så har vi utvecklat en kvalitetsdriven designmodell, fokuserad runt fyra kvalitetsaspekter: tillgänglighet, användbarhet, navigation och interaktion. Genom att utnyttja praktiska och enkla tekniker och genom att mäta deras effektivitet i att utveckla kvalitet, så försöker den här studien att bevisa att kvalitet kan användas som en praktisk resurs. Kvalitet kan garanteras i alla designprojekt som involverar ett web-baserat informationssystem, genom användning av denna modell.

[EN] The relevance of the opinion of citizens has increased in the last decade. Many government administrations have now introduced public participation processes as a necessary part of making decisions on critical aspects of governance. Although electronic participation initiatives provide citizens with access to these processes. Currently, there is no clear and accepted definition of the field due to the great diversity of theoretical proposals and the interdisciplinary nature of the initiatives. Various e-Participation frameworks and applications developed ad-hoc have been proposed to respond to a specific initiative. However, a methodological proposal has not yet been developed that covers the entire e-Participation process supported by a software tool. This thesis reviews the current literature in the field of e-Participation through a systematic mapping of the research work together with some previous relevant proposals for the area, with the aim of providing a conceptual guide to the components of e-Participation. This review analyzes the findings and groups the results in order to structure a conceptual framework for e-Participation which we call ePfw, a framework to assist in the definition and implementation of e-Participation processes. ePfw can model all the components, stages, activities and information flows that occur in an e-Participation process. ePfw incorporates a metamodel that shows a structural perspective in which the properties of the entities that participate in the e-Participation processes are specified. An assessment of the completeness and functionality of ePfwTool, a support tool for the ePfw framework, is also described and has been evaluated by various e-Participation experts, showing the results obtained. Given that there is a need to create a reliable environment for citizens to choose to participate in e-Participation processes, this thesis analyzes through empirical research the factors that directly influence trust in e-Participation initiatives. The study is carried out on the citizens in the city of Valencia (Spain) and analyzes the predominant factors that influence the procedure, the technology involved and the perceived risks and benefits of e-Participation. The results obtained are explained through models created and synthesized with the SmartPLS tool. Finally, the ePfw framework was improved by incorporating the trust factors analyzed.

Die Anwendung von Methodiken und Technologien aus dem Bereich der Softwaretechnik auf den Bereich der Umweltmodellierung ist eine gemeinhin akzeptierte Vorgehensweise. Im Rahmen der "modellgetriebenen Entwicklung"(MDE, model-driven engineering) werden Technologien entwickelt, die darauf abzielen, Softwaresysteme vorwiegend auf Basis von im Vergleich zu Programmquelltexten relativ abstrakten Modellen zu entwickeln. Ein wesentlicher Bestandteil von MDE sind Techniken zur effizienten Entwicklung von "domänenspezifischen Sprachen"( DSL, domain-specific language), die auf Sprachmetamodellen beruhen. Die vorliegende Arbeit zeigt, wie modellgetriebene Entwicklung, und insbesondere die metamodellbasierte Beschreibung von DSLs, darüber hinaus Aspekte der Pragmatik unterstützen kann, deren Relevanz im erkenntnistheoretischen und kognitiven Hintergrund wissenschaftlichen Forschens begründet wird. Hierzu wird vor dem Hintergrund der Erkenntnisse des "modellbasierten Forschens"(model-based science und model-based reasoning) gezeigt, wie insbesondere durch Metamodelle beschriebene DSLs Möglichkeiten bieten, entsprechende pragmatische Aspekte besonders zu berücksichtigen, indem sie als Werkzeug zur Erkenntnisgewinnung aufgefasst werden. Dies ist v.a. im Kontext großer Unsicherheiten, wie sie für weite Teile der Umweltmodellierung charakterisierend sind, von grundsätzlicher Bedeutung. Die Formulierung eines sprachzentrierten Ansatzes (LCA, language-centered approach) für die Werkzeugunterstützung konkretisiert die genannten Aspekte und bildet die Basis für eine beispielhafte Implementierung eines Werkzeuges mit einer DSL für die Beschreibung von Zellulären Automaten (ZA) für die Umweltmodellierung. Anwendungsfälle belegen die Verwendbarkeit von ECAL und der entsprechenden metamodellbasierten Werkzeugimplementierung.The application of methods and technologies of software engineering to environmental modeling and simulation (EMS) is common, since both areas share basic issues of software development and digital simulation. Recent developments within the context of "Model-driven Engineering" (MDE) aim at supporting the development of software systems at the base of relatively abstract models as opposed to programming language code. A basic ingredient of MDE is the development of methods that allow the efficient development of "domain-specific languages" (DSL), in particular at the base of language metamodels. This thesis shows how MDE and language metamodeling in particular, may support pragmatic aspects that reflect epistemic and cognitive aspects of scientific investigations. For this, DSLs and language metamodeling in particular are set into the context of "model-based science" and "model-based reasoning". It is shown that the specific properties of metamodel-based DSLs may be used to support those properties, in particular transparency, which are of particular relevance against the background of uncertainty, that is a characterizing property of EMS. The findings are the base for the formulation of an corresponding specific metamodel- based approach for the provision of modeling tools for EMS (Language-centered Approach, LCA), which has been implemented (modeling tool ECA-EMS), including a new DSL for CA modeling for EMS (ECAL). At the base of this implementation, the applicability of this approach is shown.

Darbe nagrinėjama programų sistemų palaikymo ir vystymo problema. Nustatyta, jog sąnaudos šiose programų sistemos gyvavimo ciklo fazėse siekia iki 80% visų sąnaudų, skiriamų programų sistemai kurti. Pagrindinis šio reiškinio veiksnys yra nuolatinis poreikis pritaikyti sistemų funkcionalumą prie besikeičiančių verslo reikalavimų, o tokios užduotys apima didžiąją dalį visų palaikymo veiklų. Nagrinėti tyrimai parodė, kad programų sistemose įgyvendintai verslo logikai suprasti sugaištama 40–60% pakeitimams atliki skirto laiko, kadangi atsakingi už sistemų palaikymą žmonės paprastai nėra jų projektuotai, todėl turi dėti dideles pastangas, kad išsiaiškintų sistemos veikimo principus. Be to, pakeitimai, atliekami palaikymo metu, yra retai dokumentuojami (ar net nedokumentuojami visai), o supratimas įgytas įgyvendinant pakeitimus lieka individualių programuotojų galvose. Tuo tarpu kiti tyrimai atskleidė, jog paprastai tik trečdalis programų sistemos kodo įgyvendina verslo logiką, o kita dalis yra skirta platformos ir infrastruktūros funkcijoms įgyvendinti. Iš to darytina išvada, jog išgaunant dalykinės srities žinias bei išlaikant atsekamumą tarp jų ir jas įgyvendinančio programinio kodo, galima sumažinti sistemų palaikymo ir vystymo kaštus. Todėl pagrindinis šio darbo tikslas yra patobulinti verslo žinių išgavimo ir vaizdavimo procesą, pasiūlant metodą ir palaikančias priemones, kurios palengvintų egzistuojančių programų sistemų suvokimą.
Darbas susideda iš įvado, 4 dalių, bendrųjų... [toliau žr. visą tekstą]The dissertation addresses the problem of software maintenance and evolution. It identifies that spending within these software lifecycle phases may account for up to 80% of software’s total lifecycle cost, whereas the inability to adopt software quickly and reliably to meet ever-changing business requirements may lead to business opportunities being lost. The main reason of this phenomenon is the fact that the most of maintenance effort is devoted to understanding the software to be modified. On the other hand, related studies show that less than one-third of software source code contains business logic implemented within it, while the remaining part is intended for platform or infrastructure relevant activities. It follows that if the most of changes in software are made due to the need to adopt its functionality to changed business requirements, then facilitating software comprehension with automated business knowledge extraction methods may significantly reduce the cost of software maintenance and evolution. Therefore the main goal of this thesis is to improve business knowledge extraction process by proposing a method and supporting tool framework that would facilitate comprehension of existing software systems. The dissertation consists of the following parts: Introduction, 4 chapters, General Conclusions, References, and 6 Annexes. Chapter 1 presents a systematic literature review of related studies in order to summarize the state-of-the art in this research field... [to full text]

It encompasses overviews of metadata repository qualities of UEML, ARIS, GRAI Grid, BPMN enterprise modelling methods and notations and their application in designing metadata repositories. ARIS method was selected as the most suitable enterprise modelling method because it encompasses the largest number of aspects of the enterprise activity. Employing this method meta-model, a metadata repository was created and integrated with the informational system of the company UAB „Klaipėdos Konteinerių Terminalas“ for more efficient management of the company’s data flows. With the help of this metadata repository data extracted from various company’s documents is grouped according to different aspects of the company’s activity: workplaces, departments, job functions, etc. The paper investigates creation of metadata repositories on the basis of UEML, GRAI Grid and BPMN meta-models and compares their qualities with those of a metadata repository created on the basis of ARIS meta-model. It has been established that application of ARIS enterprise modelling method enables to create a metadata repository encompassing more aspects of the enterprise’s activity. It allows to better identify changes in the enterprise’s documents and their place in the activity management process.

Full textAbstract:
Die Telekommunikation und die ihr zuliefernde Industrie stellen einen softwareintensiven Bereich dar - der durch einen sehr hohen Anteil von Eigenentwicklungen gekennzeichnet ist. Eine wesentliche Ursache dafür sind spezielle Anforderungen an Telekommunikationssoftwaresysteme, die i.allg. nicht durch Standardsoftwareprodukte sichergestellt werden können. Diese Anforderungen ergeben sich aus den besonderen Eigenschaften solcher Softwaresysteme wie die Verteilung der Komponenten von Softwaresystemen sowie die Verteilung der Entwicklung dieser Komponenten, die Heterogenität der Entwicklungs- und Einsatzumgebungen für diese Komponenten und die Komplexität der entwickelten Softwaresysteme hinsichtlich nichtfunktionaler Charakteristika. Die industrielle Entwicklung von Telekommunikationssoftwaresystemen ist ein schwieriger und bisher nicht zufriedenstellend gelöster Prozeß. Aktuelle Forschungsarbeiten thematisieren Softwareentwicklungsprozesse und -techniken sowie unterstützende Werkzeuge zur Erstellung und Integration wiederverwendbarer Softwarekomponenten ("Componentware"). Das Ziel dieser Dissertation besteht in der Unterstützung der industriellen Entwicklung offener, verteilter Telekommunikationssoftwaresysteme. Dazu wird die Entwicklungstechnik Objektorientierte Modellierung mit dem Einsatz von Komponentenarchitekturen durch die automatische Ableitung von Softwarekomponenten aus Modellen zusammengeführt. Die zentrale Idee ist dabei eine präzise Definition der zur Entwicklung von verteilten Softwaresystemen einsetzbaren Modellierungskonzepte in Form eines Metamodells. Von diesem Metamodell ausgehend werden dann zur Konstruktion und Darstellung objektorientierter Entwurfsmodelle eine graphische und eine textuelle Notation definiert. Da die Notationen die Konzepte des Meta- Modells visualisieren, haben sie diesem gegenüber einen sekundären Charakter. Für die Transformation von Entwurfsmodellen in ausführbare Applikationen wurde auf der Grundlage von CORBA eine Komponentenplattform realisiert, die zusätzlich zu Interaktionen zwischen verteilten Softwarekomponenten auch Entwicklungs-, Deployment- und Ausführungsaspekte unterstützt. Wiederum ausgehend vom Metamodell wird durch die Anwendung wohldefinierter Ableitungsregeln die automatische Überführung von Entwurfsmodellen in Softwarekomponenten des zu entwickelnden Systems ermöglicht. Die von den Autoren erarbeiteten Konzeptionen und Vorgehensweisen wurden praktisch in eine Werkzeugumgebung umgesetzt, die sich bereits erfolgreich in verschiedenen Softwareentwicklungsprojekten bewährt hat.The telecommunication industry and their suppliers form a software intensive domain. In addition, a high percentage of the software is developed by the telecommunication enterprises themselves. A main contributing factor for this situation are specific requirements to telecommunication software systems which cannot be fulfilled by standard off-the-shelf products. These requirements result from particular properties of those software systems, e.g. distributed development and execution of their components, heterogeneity of execution and development environments and complex non-functional characteristics like scalability, reliability, security and manageability. The development of telecommunication software systems is a complex process and currently not satisfactory realized. Actual research topics in this arena are software development processes and development techniques as well as tools which support the creation and integration of reusable software components (component ware). The goal of this thesis work is the support of the industrial development and manufacturing of open distributed telecommunication software systems. For that purpose, the development technique object oriented modelling and the implementation technique usage of component architectures are combined. The available modelling concepts are precisely defined as a metamodel. Based on that metamodel, graphical and textual notations for the presentation of models are developed. To enable a smooth transition from object oriented models into executable components a component architecture based on CORBA was also developed as part of the thesis. This component architecture covers besides the interaction support for distributed components deployment and execution aspects. Again on the basis of the metamodel code generation rules are defined which allow to automate the transition from models to components. The development techniques described in this thesis have been implemented as a tool chain. This tool chain has been successfully used in several software development projects.

Full textAbstract:
Data Warehouse support in terms of Requirements Engineering models and techniques has been extensively provided for operational level of decision making. However, it is increasingly being recognized that there are other forms of decision making that exist in an organization. These are strategic in nature and ‘above’ operational decision making.
This thesis addresses the issue of providing decision making support to both strategic and operational decision making in the same DW system. The solution starts by defining two broad categories of decisions for which decision support is needed, one for policy enforcement rule (PER) formulation decisions and the other for operational decisions. Both kinds of decisions are structured based on a generic decision meta-model developed here.
The process starts by developing two Data Warehouses, one for policy enforcement rules and the other for operational decisions. In order to identify the needed information for supporting decision making, a set of generic techniques for eliciting information is proposed. This information is stored in the DW. Again, the structure of information for the two DWs is based on a generic information meta-model developed here.
The two DWs are integrated upstream in the requirements engineering phase using an integration life cycle proposed in this thesis. It is argued that there is a need for integration following the problems of inconsistency and loss of business control that can occur. This is due to common information and differing refresh times between the two Data Warehouses.
