Information model implementation in systems architecture
Pořádek, Jiří ; Říhová, Zora (advisor) ; Tumová, Jindra (referee)
This thesis deals with a field of information modeling and its relation to systems architecture. It is divided into two notional parts -- theoretical (first and second chapter) and practical (third and fourth chapter). First chapter explains the meaning of the term 'information model', compares it to the term 'data model' and then introduce its practical use in an enterprise modeling. It also defines the term of 'systems architecture' in its broad meaning and reduces it to three narrow meaning -- enterprise architecture, information architecture and information systems architecture, while it explains their relation to the information modeling. Finally this chapter provides the base for information model implementation methodology created later in the practical part of this thesis. Second chapter introduces architecture framework called TM Forum Frameworx specialized for a telecommunication services provider. It consists of three standards for business process, information and application architecture. The second one defines specific information model which is described partly in the second chapter and partly in the appendix B of this thesis. Third chapter describes the first of two contributions of this thesis - the information model implementation methodology. This methodology is applicable to any implementation of an information model. Three sections of this chapter contains diagrams and description of three phases of the methodology - pre-implementation phase, implementation phase and post-implementation phase. In the end of the chapter there is a table containing outputs of every single activity performed during all the phases. Fourth and last chapter then describes and evaluates real implementation of the information model from TM Forum Frameworx in the systems architecture department of an enterprise providing telecommunication services. This implementation based on the created methodology and its successful results then became the second contribution of this thesis.

Cooperation model for architecture and integration areas
Rubeš, Milan ; Jandoš, Jaroslav (advisor) ; Havlíček, Zdeněk (referee) ; Zuzák, František (referee)
In today's economics, medium and large-size companies are trying to gain a competitive advantage from specialization and centralization of supporting services. This trend affects also areas of enterprise architecture and integration where they establish particular teams to support the disciplines in regular manner. Despite a lot of research activities oriented towards these topics, there are only a few focusing on organizational aspects and cooperation between enterprise architecture and integration teams. As the companies are on different levels of the maturity in both areas and focusing on different aspects of architecture and integration, there is no simple solution that could provide detailed guidelines for establishing the right cooperation approach. Goal of this dissertation is to propose a cooperation model for architecture and integration teams that should make cooperation between such teams more efficient. Integral part of the dissertation is to verify the model in real environment. The model is built on top of integration activities performed either in enterprise architecture or integration teams or both. These activities are categorized into particular integration areas and relations are identified between integration areas and architecture areas defined according to TOGAF architecture framework. The resulting model is then being used to depict various kind of cooperation between architecture and integration teams based on the companys' integration goals. Verification of the model is performed in financial enterprise in two cases and confirms the benefits of the model.

Enterprise architecture
Dvořák, Jaroslav ; Selčan, Vladimír (advisor) ; Buchalcevová, Alena (referee)
This work analyses the enterprise architectures questions. Enterprise architecture is relatively familiar in the field of informatics today. It covers discipline of modeling and planning development of information technology, especially in wide organizations. Enterprise architecture is an important branch under the conditions that system complexity exceeds brain capacities of workers. The first part deals with analysis of enterprise architecture, primarily structure, content and relationship to whole enterprise. The most important part of this section is a characterization of enterprise architecture frameworks that facilitate entire process of formation. The second part deals with introduction of three essential architecture frameworks: Zachman, TOGAF and FEAF. Subsequently FEAF is compared with two previous frameworks. The conclusion of this work contains short comparison of features and contents all three mentioned enterprise architecture frameworks.
