Service-Oriented Architecture (SOA) is a mechanism for achieving interoperability between heterogeneous systems. SOA enables existing legacy systems to expose their functionality as services, without making significant changes to the legacy systems. Migration towards a Service-Oriented Approach (SOA) not only standardizes interaction, but also allows for more flexibility in the existing process. Web services technology is an ideal technology choice for implementing a SOA. Web services can be implemented in any programming language. The functionality of Web services range from simple request-reply to full business process. These services can be newly developed applications or just wrapper program for existing business functions to be network-enabled.
