| Abstract [eng] |
Nowadays the terms SOA (Service Oriented Architecture) and event driven systems are often used when talking about systems with large scalability, performance and interoperability. In fast changing business world it is vital to have systems that could be easily changed whenever new functionality is needed. Using service oriented architecture companies can easier adapt its business process to changed business rules. Even though there are a lot of articles and publications about event driven systems and their advantages, but the system architect who decides to build an event driven system is facing the problem: how to model and describe events of the system. Obviously, that there are no popular and widely accepted methodology for event driven system modelling. The goal of this work is to develop a methodology for modelling an event driven systems. This methodology describes the metamodel for event modelling and the usage of the event model in system development life cycle. The developed methodology for modelling and implementation of event-driven information systems was used for making a model of publications portal prototype. Usage of this methodology in system design process adds more clarity, because all the events, which can be generated in the system and their types, are described in one diagram – event model. The event model elements can be used in other model diagrams, such as sequence or state machine diagrams. |
