Nowadays the computer world is almost migrating from the tightly coupled architecture to loosely coupled architecture directly or indirectly. There are many intentions of Enterprise Application Integration in the organizations to achieved desired functions. The main objective of the Enterprise Application Integration is to implement integration layer between heterogeneous and/or homogeneous systems using Service Oriented Architecture in the direction of achieving the loosely coupled architecture. The integration architecture we have today is very limited and need to improve it as agile as possible. The reusability is not the new thing for software industry; it has been playing the crucial part in the software life cycle development process from last decade. Software industry has achieved the powerful accomplishment in throughput and preeminence because of reusability in software development process instead of creating same thing again and again. In this paper, we will discuss about Enterprise Application Integration using Service Oriented Architecture for achieving loosely coupled architecture directly or indirectly with the help of Web Services or Messaging Queue services.

Keywords: SOA: Service Oriented Architecture, WS: Web services, WSDL: Web Service Description/Definition Language, W-SOA: Web Service Oriented Architecture, ESB: Enterprise Service Bus.
