Enterprise Service-Oriented Architecture  

Enterprise Services-Oriented Architecture (Enterprise SOA) is SAPs open architecture for adaptive business solutions. Enterprise SOA creates a gradual path to flexible, service-centric system landscapes and allows a non-disruptive transition of existing applications and architecture for more flexibility and value.

The fundamental premise of Enterprise SOA is the abstraction of business activities or events, modelled as enterprise services, from the actual functionality of enterprise applications. Aggregating Web services into business-level enterprise services provides more meaningful building blocks for the task of automating enterprise-scale business scenarios. Enterprise services allow IT organizations to efficiently develop composite applications.
