Abstract

Enterprise Architecture (EA) Modelling aims to analyze an organization in terms of its components, IT systems and business processes. Current modelling approaches are based on Service Oriented Architecture (SOA) whereby components publish interfaces of operations that are used via message passing. It has been argued that SOA leads to tight coupling between components and does not handle complex component interactions, with resulting maintenance difficulties. Event Driven Architecture (EDA) is an alternative strategy, based on listening for events, that is designed to address SOA shortcomings. However, there are no EA modelling technologies based on EDA. This paper reviews EA, SOA and EDA, identifies EDA characteristic features and proposes modelling and simulation technologies that are introduced through a simple case study.
