Modeling EAI

* Enterprise Application Integration † Co-financed by FONACIT through the S1-2001000792 Abstract Software integration has been a solution to the problem of connecting dissimilar systems for many years. This integration is still a challenging issue. EAI (Enterprise Application Integration) is defined as the process of integrating enterprise systems with existing applications. Since software integration research has yielded a variety of different concepts, we survey and discuss this terminology. EAI arise as an evolution of the CASE technology approach. The main goal of this work is the modeling of EAI in order to obtain a more organized and unified view of the main aspects involved. The EAI model presented in this work was constructed extending the known Brown’s Conceptual Model of Integration (BCMI). One of the interesting contributions of this paper are the identification of architectural styles and patterns and the specification of a quality model, based on the international standard ISO 9126-1 for integrated enterprise systems. This quality model specifies the quality characteristics that the systems in the EAI domain should hold.
