Services-based application design
The first step to start designing BPEL services is to document the business process
using an easy-to-read visual notation. Services interaction occurs through a standard
WSDL format. WSDL is also used to represent the interfaces exposed by the service
to the systems outside:
SOA is an IT strategy that organizes discrete functions services from enterprise ap-
plications. SOA enables an enterprise to quickly deliver for business requirements by
combining and reusing existing discrete functions services.

• Oracle Enterprise Service Bus (OSB) routes the messages and invokes
back office services
• Back office services serve the users' requests
SOA Suite
As an architect, one should know the components available within SOA Suite and
how to leverage these components to architect and design the services, and then use
these services to create consumer applications faster and cheaper. The list of SOA
Suite components with brief descriptions for the capabilities of each component is as
follows:
