BPEL
Černý, Ondřej ; Selčan, Vladimír (advisor) ; Buchalcevová, Alena (referee)
The thesis is dealt with the question of Business Process Execution Language. First of all, the work is focused on two main approaches which make use of the BPEL language. It concerns the approach to both service oriented architecture (SOA) and Business Process Management. The thesis subsequently defines and shows the features of SAO and BPM and determines the key role of BPEL in SOA and BPM. The important part describes alignment of SOA and BPM which shows individual problems of alignment of both approaches by the help of BPEL language. Furthermore it shows the difference between business and IT, which is necessary to overcome. After the two basic trends, that use BPEL language, are introduced the work attends directly to the BPEL language. After the basic characteristics are explained, BPEL language is defined and filed into history. A short paragraph is devoted to BPEL engine, which performs the executable business processes. Consequently the important elements of BPEL language and life-cycle of BPEL process are described. The second part of the thesis is concluded by disadvantages of BPEL language. The last part aims to compare selected tools for the use of BPEL language on the basis of their features defined by criteria. As firstly showed in appendix, there is a possibility to transfer business process from a model to an executable form. Furthermore there are also examples of practical BPEL language usage for service orchestration and for complete usage of the BPM life-cycle.

Providing ERP system as a service for small enterprises
Hrabal, Jan ; Basl, Josef (advisor) ; Selčan, Vladimír (referee)
Enterprise systems have been used since the 1970s. They have changed over the time but their main purpose - to automate and streamline the corporate processes, is still the same. However the scope has increased and the enterprise systems became very widespread. They integrate many usefull utilities into one system and have moved from the mainframes to common desktop computers. The abreviation ERP is very well known in today's IT world. It would be really difficult to find a large or midsize company which does not use the enterprise resource planning system. Yet the situation is dramatically different at the small enterpirse market. Due to theirs complexity, ERP systems are expensive. Many small companies are unable to afford heavy investments into the software they are using. Such enterprises can use the lightweight versions of the commercial solutions or not to use ERP systems at all. There is a new business trend - the SaaS business model. It is based on providing the access to the system over the network for regular fees. These fees are smaller than the licence ones so that it is easier for small companies to get up to ERP systems that would be too expensive for them otherwise. Even big software companies (such as SAP) have been getting engaged with the adoption of the SaaS recently. The IT experts say the SaaS business model is to be very prospective. The goals of this dissertation consist of the analysis of providing the ERP system as a service and the description of technical and processionary aspects that are mandatory for succesful adoption of the SaaS business model. A proprietary solution of the ERP system will be provided as a part of this thesis. The solution would be designed and developed especially for purposes of the adoption of the SaaS model.

Design, development and implementation of FileMaker system
Kábrt, Jakub ; Selčan, Vladimír (advisor) ; Buchalcevová, Alena (referee)
This thesis deals with the design, realization and implementation of database IS FileMaker. FileMaker is a development environment for creating database tables and their relationships as well as the Graphic User Interface (GUI). It deals with the characteristics of the environment, a description of the basic components that are used to create both functional and user part of the basic processes of development and finally the advantages and disadvantages of the competition. In detail, it describes the life cycle of a system created for a company, such as practical knowledge of the GUI interface or scripts. It deals in detail with ability to share databases using a number of protocols (such as FileMaker network, Web Publishing, SQL, ODBC, JDBC), the possible addition of hardware or software components. The conclusion is dealing with SWOT analysis of environment, where key features are highlighted, weaknesses, opportunities and possible threats.

Approaches to transformation of process description to BPEL
Císař, Daniel ; Gála, Libor (advisor) ; Selčan, Vladimír (referee)
In this work, I dealt with the field of Business Process Managent and Service Oriented Architecture. First I tried a comprehensive conceptual view of both through the definition of important principles. In BPM as a disciline I identified "life-cycle" as the most important principle for process optimization tools. For service-oriented architecture, I had to reduce the view to important principles related to composition of services. An important starting point in my work are the definitions of processes and services and their roles in BPM systems. It is a simplified view that helps connect modeled processes to Web services. Web services and orchestration is the most popular and most common usage of the service-oriented architecture. Composition is another important building block of SOA and is the basis for more realistic goals of SOA, such as greater enterprise agility, more efficient utilization of resources in the enterprise, etc. BPM discipline combines multiple elements and as it is typicaly multidisciplinary it combines process management and optimization through tools. These tools historically perform their roles well, but companies are now in a very competitive linked environment and must to behave differently. In my work I have stated firstly why would these areas could be beneficial to each other. The next part focused, what is the relationship with the life-cycle process for BPM and how it fits into the life-cycle services in SOA. Finally, I analyzed the current state mapping of BPMN, the most common notation for expressing processes in BPM, to BPEL. BPEL describes a process, but it is expressed as a programmatic sequential process, which is also executed in digital form. At work I have examined the role of the new version of the BPMN notation 2.0.

SOA Governance
Karkošková, Soňa ; Selčan, Vladimír (advisor) ; Buchalcevová, Alena (referee)
This bachelor thesis is focused on the processes which are used in the service oriented architecture (SOA) enviroment of IT for its governing -- the SOA Governance. That thesis deals with the reasons for an implementation of the service oriented architecture as a resource for fast and effective encompassment of dynamicaly floating conditions of an entrepreneurship. Further the thesis analyzes characteristics of services which are necessary for availing the service as the part of the service oriented architecture. The attention is paid to the ITIL library and ITSM. In that thesis are described the processes that are upheld within the ITSM in the service design phase, in the service transition phase to the productive operations and in the run-time phase of the productive operations of the service. Further is paid attention to the process of continual service improvement. Further the thesis deals with the SOA Governance - Reference Model and the SOA Governance - Vitality Method in more detailes. The thesis analyzes processes of the SOA Governance feasible in the service design phase and in the service run-time phase. The thesis adverts to direct realitonship and synergy between individual phases of the service life-cycle governing of the service oriented architecture and the service life-cycle governing in accordance with ITIL and further adverts to the need of the integrated governance. There are pointed out the basic steps of the implementation of the SOA Governance including the time progress in the example of the practical realization.

Comparison Tools for the development of SOA-ready Business Services
Simetinger, František ; Gála, Libor (advisor) ; Selčan, Vladimír (referee)
Today's business informatics solves many problems issues that complicate the management, planning and financial efficiency. Modern approaches and technologies offer several ways to deal with these problems. But it is not always possible at first glance identify the correct way, because it usually solve only partial problems in modern business informatics appear. One of the most sophisticated approaches that solve these problems is service oriented architecture. Service oriented architecture is enabled to effectively improve the business agility, is focused on supporting business goals and is enabled to integrate business applications transparently according to enterprise requirements. But implementation of services oriented architecture principles in business computing isn't trivial procedure. The service oriented architecture brings a lot of changes, for instance into business informatics management. One of the most important issues is alone services development, which are the essence of the service oriented architecture. This thesis is aimed at maintain of service oriented architecture principles during development of business services in development tools, which are intended for development of these services.

Kinská, Marcela ; Stanovská, Iva (advisor) ; Selčan, Vladimír (referee)
This diploma thesis defines the issue of software requirements engineering and the implementation of software requirement into IS/ICT projects. One of the aims is to highlight the importance of systematic requirements management to successful IS/ICT projects. The theoretical part of thesis includes requirements definition, requirements typology and qualitative parameters of good requirement and actors, that are involved into the process of requirements management. The practical part of this thesis defines the process of requirements management general accepted methodologies of as it is specified in the internationally recognizable methodologies. Author's own contribution is the definition of a methodological process for managing requirements specifications, based on rigorous methodologies and extended to reflect author's practical experience. Methodological approach is tailored to the needs of smaller software companies and small to medium scale IS / ICT projects, and, if necessary, is further extendable. Another practical benefit of this thesis is the recommended methodology for change management requirements. Proposal process is based on the ITIL set of best practices; sub-threads are adapted to be able to meet the change management requirements and the broader business environment infrastructure. This methodology emphasizes an individual approach to the requirement. There is a recommendation of appropriate software tools for development and management requirements support divided into partial ITIL processes.

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.
