Application Integration Architecture
Application Integration Architecture (AIA) allows developers to build composite applications - and will allow customers to integrate various applications (like 11i/R12, Siebel, PeopleSoft, third party application and custom applications), in such a way that it will not be affected by upgrades of certain components.
AIA will also be used in Fusion Applications.
Currently, Oracle offers two components with AIA:
- Industry Process Integration Packs (PIPs)
- Industry Reference Models
 Process Integration packs
Process Integration Packs (PIPs) are used to integrate applications across product lines.
 Reference models
Oracle's Industry Reference Models are documented industry best practices that can be used to build a more responsive IT infrastructure, while protecting your existing technology investment. They provide documented business processes that allow for the creation of custom, integrated process flows across heterogeneous environments.
