A messaging-based architecture for enterprise application integration

This paper discusses a messaging-based architecture for enterprise application integration (EAI). The first generation of enterprise application integration focused on the problem of making data held by various enterprise applications available from a common location and in a common format. The current generation of EAI goes beyond this by also propagating and controlling the flow of business events from application to application as they occur. A flexible, robust and scalable messaging infrastructure is essential to this form of active integration.
