The aim of the Diploma thesis is to evaluate the selected object-oriented (OO) methodology as it was defined by its author, on the basis of defined criteria, whether it is applicable in practice when designing an information system, with a main focus on analysis of the new core banking system supporting key processes of payment institution and Forex broker. Diploma thesis describes selected OO methodologies and notations used in the analysis and design of information systems. Further, it focuses on the evaluation of the real usage of selected method (Unified Process) in the environment of payment institution. It confronts the theoretical definition of a selected OO methodology with its application during the analysis of IS through practical demonstrations created within the case study.
