No enterprise system is an island. To effectively utilize Oracle BRM, it is inevitable that it be integrated with other enterprise systems. Examples of commonly integrated systems include CRM systems, order management solutions, custom user interfaces, and provisioning systems, to name a few.
Of course, Oracle has a preferred approach to BRM integration: the Application Integration Architecture (AIA) framework. AIA is a good option when you are trying to integrate BRM with other Oracle products (such as Siebel and OSM). AIA brings Oracle defined best practices to the table in the form of a common canonical data model and predefined orchestrations between products for common use cases.
