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.
