Enterprise Application Integration using Service Oriented Architecture with Web Service Aggregation Pattern

Abstract

Enterprise Application Integration (EAI) is assembling heterogeneous applications to communicate each other and reducing their complexity. Service Oriented Architecture (SOA) has been offered standard, principle and architectural design style with best IT enterprises align. As market growing, the new technologies, systems and databases has been introducing rapidly to achieve the demands and current market goals. Legacy systems are still playing the significant role in today's electronic business even introduces new and powerful systems, applications and databases. But still it could not replace Legacy system because huge amount of money invested by organizations. The proposed system will have an integration layer which is exposed as a service to achieve loosely coupled architecture using service oriented architecture. It can be web service based or Messaging Queue based scenario to achieve this. One of the main objectives for efficient service oriented architecture is to achieve interoperability between the disparate systems. The motivation behind of integration layer is to save money and time in future for electronic business by providing generic pattern to minimize efforts of developer to do work from scratch.
