The global economic environment nowadays becomes so competitive, all enterprises suffer a challenging and confronting adversity. Due to the knowledge economy era, all enterprises need to emphasize the internal information management and application. Therefore, the Business Intelligent (BI) software turns into the best solution for an enterprise. As each enterprise has different structure and behavior views, the BI definition is required to adapt to the enterprise environment. To resolve this problem, an enterprise must increase the business cost, and system managers are demanded to modify the programs repeatedly. Our research aims to assist the BI software by defining a model of Architecture-Oriented Business Intelligent (AOBI) which helps analyze and design the software with ease. The AOBI model is to describe the structure and behavior in one unity. Using this approach of structure and behavior in one unity, developers would devise and adjust the BI software more flexible and adaptable. This study distinguishes into three parts. The first part is to introduce the architecture theory. The second part is to explain how to build up an architecture model. The third part is to propose an AOBI model. Inside the thesis, BI structure elements, operations, and structure and behavior in one unity are elaborated. Also, using AOBI model assists system developers to construct the BI software for an enterprise. In the future, we would further our efforts on the implementation, testing, cost and performance management of the AOBI software. The BI software contains other software, for example, Key Performance Indicator, Data Warehouse, Data Mart, Data Mining and On-line analysis processing, etc. We may construct the above software using the architecture model, too.

With the significant progress of information system, information technique has been the essential surviving key to a business. Enterprise adopts various information systems so as to be able to aware of the ever-changing environments coming from either internally or externally and still maintain stable and reliable management mechanism. Enterprise Resources Planning (ERP) has been widely applied to the integration of companies¡¦ internal processing systems. Nevertheless, focusing too much on either structure view, or process view, or isolated structure-process views always hinds the success of implementing an ERP within a company. Consequently, to be classified as a blue ocean enterprise, this research urges companies describe ERP with Distribution ERP Architecture Model (DERPAM), hence structure-process-integration constructing distribution ERP systems. In such case, combination of 80% distribution ERP and 20% core competence of each unique company becomes highly achievable. Outstandingly, DERPAM helps companies derive an optimized distribution ERP.

The global economic environment nowadays becomes so competitive, all enterprises suffer a challenging and confronting adversity. Due to the knowledge economy era, all enterprises need to emphasize the internal information management and application. Therefore, the Data Warehousing (DW) turns into the best solution for an enterprise. As each enterprise has different structure and behavior views, the DW definition is required to adapt to the enterprise environment. To resolve this problem, an enterprise must increase the business cost, and system managers are demanded to modify the programs repeatedly. Our research aims to assist the DW by defining a model of Architecture-Oriented Data Warehousing Framework (AODWF) which helps analyze and design the software with ease. The AODWF is to describe the structure and behavior in one unity. Using this approach of structure and behavior in one unity, developers would devise and adjust the DW more flexible and adaptable. This thesis distinguishes into three parts. The first part is to introduce the architecture theory. The second part is to explain how to build up an architecture model. The third part is to propose the AODWF. Inside the thesis, DW structure elements, operations, and structure and behavior in one unity are elaborated. Also, using AODWF assists system developers to construct the DW for an enterprise. In the future, we would further our efforts on the implementation, testing, cost and performance management of the AODWF. The DW contains other software, for example, Business Intelligent, Data Mart, Data Mining and On-line analysis processing, etc. We may construct these software using the architecture model, too.

This thesis presents a semantic-based modeling approach for describing Service-Oriented Architectures (SOA). Ontologies are utilized as a major representation mechanism for describing various elements available in the architecture. The methodology proposes an architecture specification mechanism to constuct a unified ontology that enables transition from design concerns to the modeling elements. A multi-level modeling is also achieved by employing Model-Driven Engineering (MDE) techniques to describe various models at different stages of the software architecture. This aims to organize service-oriented models within a number of architecture viewpoints in order to provide an architectural perspective for SOA. The use of ontologies for model specification also allows us to make use of ontology mapping to specify the transformation between different models. Additionally, we present a case study to demonstrate the proposed methodology on a real-world healthcare scenario.

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. / Information Science / Unrestricted

This work deals with designing a library of processor models used in embedded systems. Processor architectures are described using the ISAC language. The ISAC language is one of several outcomes of the Lissom project that is taking place at the Faculty of Information Technology, BUT, Brno. The beginning of this work is aimed to provide the introduction to processor architectures used in today's embedded systems. Remaining sections are devoted to presentations of exemplary processor architectures and the description of their implementation. This work is finalized by concluding the gathered experience with emphasis on the suitability of the ISAC language for architecture description and the efficiency of its simulation.

Modelos de arquitetura têm sido utilizados para permitir o desenvolvimento mais adequado e estruturado de sistemas, desde os mais simples até os mais complexos. A utilização desses modelos em sistemas embarcados, principalmente quando se trata de sistemas embarcados críticos, como é o caso de veículos aéreos não tripulados (VANT), visam a permitir conformidades de padrões, redução no tempo de produção, redução e facilidade no processo de manutenção e desenvolvimento. Sistemas embarcados críticos possuem requisitos específicos, tais como alta confiabilidade e resposta em tempo real, segurança e desempenho. A definição de um modelo arquitetural que permita que esses quesitos sejam levados em consideração, propicie o atendimento aos padrões, além de permitir o desenvolvimento correto e acelerado é inovador, permitindo que não só a comunidade científica venha a ter benefícios com a sua concepção, mas também a indústria brasileira possa ganhar. Nesse sentido, este trabalho desenvolveu um modelo de arquitetura para a interconexão de sistemas aéreos não tripulados (SANTs) em Unified Modeling Language (UML)/System Modelling Language (SysML) denominado LARISSA (Layered ARchitecture model for Interconnection of SystemS in uAs). Como resultado deste trabalho foi possível a modelagem e especificação completa de um SANT fazendo uso desse modelo e a realização de diversos experimentos que permitiram validar o LARISSA. Os experimentos, focados na parte de comunicação, permitiram a concepção de um simulador de redes de VANTs. Os resultados obtidos demonstraram a eficiência e a eficácia do modelo de arquitetura LARISSA, além da sua flexibilidade em permitir que diferentes experimentos possam ser realizados, o que auxilia na obtenção de dados que facilitam o processo de certificação desses VANTs. / Architecture models have been used to allow more adequate and structured development of systems, from the simplest to the most complex. The use of models in embedded systems are used to enable compliance standards, reduction in production time and ease of maintenance and development, especially when it comes to critical embedded systems such as unmanned aerial vehicles. Critical embedded systems have specific requirements, such as high reliability and real-time response, security and performance. The definition of an architectural model that deals with these requirements and standards and provides the service to standards allowing the correct and fast development is innovative and will provide benefits to the scientific and industrial communities. In this sense, this work developed an architectural model for the interconnection of Unmanned Aerial Systems (UAS) in Unified Modeling Language (UML)/System Modelling Language (SysML) called LARISSA (Layered ARchitecture model for Interconnection of SystemS in uAs). As a result of this development it was possible the modelling and specification of a complete UAS and the conduction of several experiments that allowed LARISSA validation. The experiments focused on the communication enabled the design of a UAV networks simulator. The results showed the efficiency and effectiveness of LARISSA architecture model, as well as its flexibility in carrying out different experiments, which helps in getting data to facilitate the certification process of these UAVs.

Vývoj v informačním systému neustále zvyšuje nároky na účinnou, efektivní a adaptivní spolupráci mezi komponenty systému, aby se vyrovnal se změnami v systému a zaručil tak nejlepší výkon. K dosažení těchto požadavků byly zavedeny dva hlavní přístupy. Přístup k adaptaci umožňuje informačnímu systému přizpůsobit se změnám v kontextu informací systému a jeho okolního prostředí na základě adaptační strategie. Přístup ke zvyšování informovanosti zase napomáhá sledovat informace o kontextu a rozpoznat změny, které mohou proces adaptace vyvolat. V této práci představujeme obecný kontextově orientovaný model vlastní adaptivní architektury pro podporu softwarového systému s adaptačními funkcemi, které zaručují dostupnost systému, provozní podmínky a výkon. Navíc poskytujeme dvě případové studie v reálném životě jako důkaz konceptu použitelnosti našeho navrhovaného adaptačního přístupu.

In general, a common reference architecture can be derived for Software as a Service (SaaS) architecture. However, while designing particular applications one may derive various different application design alternatives from the same reference SaaS architecture specification. To meet the required functional and nonfunctional requirements of different enterprise applications it is important to model the possible design so that a feasible alternative can be defined. In this thesis, we propose a systematic approach and the corresponding tool support for guiding the design of the SaaS application architecture. The approach defines a SaaS reference architecture, a family feature model and a set of reference design rules. Based on the business requirements an application feature model is defined using the family feature model. Selected features are related to design decisions and a SaaS application architecture design is derived. By defining multiple application architectures based on different application feature models we can even compare multiple alternatives and based on this select the most feasible alternative.
