The Research And Implementation Of Data Integration In Enterprise Application System

Today, what we face is the ages of information explosion. Much information has grown exponentially. More and more available data resources scatter in each station, such as document system, database system and some existent systems etc. According to the different need, each unit adopts the different development tool and operating system to build system at the different period. However, because each system can't effectively implement information share and exchange, the traditional system will inevitably lead to information isolated island, application isolated island and resources isolated island. A great deal of information has been "locked" in the central database of each islet. Moreover, each "isolated island" can't implement the meaningful exchanges according to the requirement of the customer. It's useful to establish new application system that may integrate the worthy data in original system in order to share the information via Internet at the larger scope and utilize the information resources more effectively. The best way to resolve these problems is to build up data integration system, which could efficiently integrate the outside and inside resources of system and promote its resources share.The idea of building up a general interface of Data Integration in Enterprise Application System (DIEAS) is proposed in this thesis in order to make the heterogeneous data visit more effectively in internal enterprise, implement the data exchanging and make the resources shared between enterprises applications.
