Information Reusability Technology's Research And Application Based On SOA

Nowadays as the rapid development of information technology, enterprises informatization management is becoming a valid way of making enterprise more competitive. However, due to the business requirements for enterprise's kept changing, more and more legacy information systems that used in enterprise or among enterprises are arise. It's common that these legacy systems are base on different development platform meanwhile having many same similar modules, which cause little connections and resources' low reusing between systems. So it's not easy to carry out the information progress of enterprise.The Services-Oriented Architecture is a new architecture in software field, which dates from early component distributed computing model. Its advantages are more reuse, more flexibility, more expansibility and more commonality. It can decrease couplings and increase the reuse among systems to the maximum extent by adopting SOA. It's more useful when the heteroid systems need to communicate with each other while they are running on different platforms and developed by different technologies.After analyzing the current environment in enterprise application integration, such as what technologies used in integration, the characteristics of different methods, the text posed a new method to integrate enterprise applications. And described a solution to implement SOA in detail, in the end, gave out a example to illustrate how to deploy SOA and come to a conclusion how to reuse information by SOA.
