Research On Data Integration Of Heterogeneous Databases Based On Middleware Technology

With the sustaining development of the scale of company, in a single company, every department will become a data source. And each data source has its own framework; all of these data constitute the different data source of the company. This phenomenon will lead to the requirements that more and more company need to visit all sorts of data source. In order to meet this demand we need the system, which can support the integration of the different data source.To solve the problem of heterogeneous information between enterprises, and realize the data sharing, this paper put forward the scheme of data integration based on middleware technology. There we using CORBA and XML technology to realize the middleware. CORBA (Common Object Request Broker Architecture) is a technique of distributed object, it can implement the transparent exchange visits of distributed heterogeneous data source by the use of the core of CORBA, ORB; XML (eXtensible Markup Language)is a kind of meta-markup language, which provides a format that describe data. Through the transform between XML and relationship data pattern, different data pattern can be unified and the heterogeneity of data source can be cleared up.
