AIA

AIA - Oracle's SOA Architecture for PIP development.
AIA - application integration architecture
SOA - Service oriented architecture
PIP - Process Integration packs

In the journey from EAI to SOA, somewhere people started using BPEL for building integration flows. XML, XSLT, Adapters are the common technologies, whats new is WebServices or more specifically WSDLs.

In the Oracle eco system, there are many packaged Applications like Ebusiness suite, Siebel, Jd Edwards , Peoplesoft etc. And It's a common requirement to have integration flows between them in various customer implementations. So in Oracle we offer PIPs build over SOA middleware using AIA architecture.
