Event-Driven Architecture is gaining an important role in component system design, for being scalable, highly flexible and for their concurrency. Their advantage of containing decoupled components is seen as a solution when modelling complex systems with heterogeneous components. However, developing event-based systems is very complex. On top of that, there are no means to analyse and explore them due to the non-determinism and for being unintuitive. Therefore, this thesis focuses on these problems and provides a solution for model description, model visualization, exploration, and analysis. The technology used for the visualization is Neo4j, a graph database platform, which has its own query language. The developer will have the possibility to describe the model using a developed domainspecific language, explore it with a detailed view of service workflow including service dependencies, and to perform a static analysis on the model in order to check for possible design errors at the design time.
