The Application Integration Architecture (AIA) is a product from Oracle and is available in Releases. The current release is 2.01. Release 2.1 is planned in the next several months.
Here’s a graphic looking at what AIA consists of. I’m going to focus on the bottom of the diagram initially.

Starting at the bottom, we reiterate that the Fusion Middleware SOA Suite is the foundation. Then on top of it is the Foundation Pack. Above it are two possible layers. One is a custom integration written within an organization using the Foundation Pack.
The other layer is a set of Process Integration Packs (PIPs) which Oracle has already created using the Foundation Pack layer.
A PIP is a pre-built specific integration between two applications. Oracle has released and continues to release new PIPs each quarter. The reason for PIP’s is that Oracle now has a number of applications they own and they realize that customers are wanting better ways to integration the information between them. Many customers have PeopleSoft, Siebel and the E-Business Suite installed. They want ways to ensure that changing customer information in one application is reflected in the others.
To make things a bit more confusing there are two types of PIP’s.
The first helps share information between two specific applications. This type of PIP is industry-agnostic but requires two specific applications like Siebel and E-Business Suite.
The second type of PIP is designed for vertical industries like Telecommunications.
To see the current list of both types you can visit here.
What you see is several PIP’s for integrating Siebel CRM and the E-Business Suite.
These are only the beginning as Oracle works to provide seamless sharing of information among the many applications they now own.
Now let’s drill down into the AIA Foundation Pack to see what it offers. That’s going to be of great interest to organizations wanting to do their own custom integrations while leveraging the capabilities Oracle provides.
