Standardizace orchestrace v prostředí služeb / Standardization of service orchestration

This thesis is focused on comparison of common standards used for service orchestration. Orchestration is one of main terms in service oriented architecture, which is a considerable trend in information systems development. This paper is divided into four main parts. The first chapter describes services as a part of current information systems. Definition of service oriented architecture is another subject, where service is a main component for system development and integration. Description of principles of service oriented architecture, that are describing its basis, is the last part of this chapter. The next chapter belongs to coordination of service cooperation, where we can find two basic approaches -- orchestration and choreography. The intention of this chapter is to create theoretical definition of both terms and to compare them. The third part is focused on orchestration methods standardization, where the main standard is BPEL. The history and reasons of creation are mentioned in the beginning, while next section concerns principles of BPEL. Following part describes the version of BPEL called BPEL4WS. Specification of its structure is a main primer for comparison with the latest version named WS-BPEL. The major changes are mentioned in this section. The last chapter is devoted to practical comparison of standards mentioned above. At first, there is created a sample process, based on real situation. The process contains the most important parts of BPEL language. Afterwards, the process is divided into parts, where each of them represents one activity. During description of these parts there is made the above mentioned comparison. The end of the practical part contains main conclusions that were found in this chapter.
