Data Share-and-exchange Platform Based On Middleware

In recent years,with a wide range applications of Internet,The demand of all communications in the exchange sector has a deeply development than before.But the problems left over the past heterogeneous system restrict this development.The problem comes from the continuous expansion of the old applications and the continuous increasing new applications.The various industries,government departments have chosen a different hardware platform,network environment and different database systems.The issues lead the variety application model, non-standard data exchange of multiple systems,non-standard of network,data sharing and the synchronization of database systems resulted in "Information Silo" phenomenon.In recent years Data Exchange Platform has been attached to various industries. Various data exchanging technologies spring up quickly.Such a cost-effective way meet a lot of industries,business needs,while the network problem is still exists,the platforms fall in trouble when the net does not work.Therefore not only a cross-platform,but also a cross-platform which is cross-network is especially important.In recent years,the middleware technology develops rapidly for its superior performance cross-platform.Middleware is a kind of software rather than a software platform.It has the principles of data exchanging in the middleware and which has its own way of data processing.So it's no need to consider the specificity of the external software platform.So it that middleware is applied to the Data Exchange Platform is inevitable.This article studied the technology related to the Data Exchange Platforms and middleware,design and develops a middleware-based data exchange and sharing platform,which can be used for data exchanging of heterogeneous database.And it achieved cross-platform,cross-network and is transparent to the user.This article also gives its own unique point to the mapping algorithm and principles.A Middleware-based platform for data exchange is different from the existing Data Exchange Platform.It overcame the shortcomings created by the restrictions of system and network in the existing Data Exchange Platform.The former Data Exchange Platforms were produced to meet the need of data exchanging of the existing systems,and they had a lot of limitations.Where the system or network environment,even the versions of the database system changed,it can lead to the failure of data exchange.Middleware-based Data Exchange Platform can be truly cross-platform,network and the underlying database system for data exchanging,and be easy to operate for the common users,because the data exchanging operation is completely transparent to users,and users can get the needed result without complex operation.
