"SOA is an architectural paradigm whose goal is to achieve loose coupling
among interacting 
software applications. Applications invoke a series of discrete services in
order to perform 
a certain task. A service is a unit of work done by a service provider to
achieve desired 
end results for a service consumer." Amir Shevat

(Service-Oriented Architecture) Formerly called a "distributed objects"
architecture, the 
SOA term was coined at the turn of the century as Web services were
evolving. CORBA and DCOM 
are examples of earlier SOAs. See CORBA, DCOM and Web services. - Computer

"The SOA abstracts and exposes business functions as services that connect
multiple business 
applications in homogeneous or heterogeneous environments." Oracle magazine
