This article lists the core functions of an EAI platform. See EAI Convergence for an example of actual stacks from TIBCO and IBM.
The integration platform functions and the core integration services enable the integration platform to play the role of an active intermediary between the transport-connected services. The platform functions and core integration services constitute […]

One of the key features setting this architecture apart from the traditional EAI and SOA implementations is the idea of document centric processing. In short, we replace the traditional API- and RPC-style integration with exchange of documents.
Tradition
The tradition of integration is deeply rooted in the concept of API. I am […]

The following provides a brief overview of ‘integration technologies’. The purpose of it is two-fold.

This appendix outlines a set of common EAI patterns and their related concepts.
The purpose of this appendix is to compile a set of common EAI patterns that will provide a basic pattern language for the purpose of this EAI architecture. We do not look at the patterns in detail; where necessary, this document refers […]
