Between each node database there must be different in the distributed heterogeneous database system, so how to resolve these different (It's said that realize the mutual transformation between heterogeneous databases) was an basic problem in the heterogeneous database system. This paper analyzes the system structure and the conversion mechanism for the distributed heterogeneous database and the realization of the conversion module theoretical including the conversion information extraction module, structural conversion module, structure formation module and put forward a concrete realization solutions.

Based on the in-depth study of the existing database synchronization model, in order to improve the cross platform ability of the system and facilitate the construction of small and medium-sized enterprise information platform, this paper proposes a heterogeneous distributed computing scheme based on Web service. The scheme uses JMS to realize the message transmission between systems, and uses web service technology to realize cross platform data reading and writing. In the aspect of distributed transaction processing, the two-phase commit protocol is improved to reduce the probability of system deadlock and effectively ensure the consistency of distributed database data. In order to improve the performance of distributed database system, cache technology is introduced, and the way of integrating cache and database transaction processing is proposed, which effectively ensures the validity of cache data. The architecture is oriented to program developers, who can develop efficient and convenient distributed database system on the basis of this architecture. Finally, this architecture is applied to the background management system of mobile express service. The running results show that the architecture can well meet the business requirements of distributed heterogeneous database system synchronization.

Database technology is of great variety, structure diversity, solving data integration and exchanges sharing of the heterogeneous database system have became the important problem in all fields. Because of XML is the very important data exchange technology to realize data exchange and transmission ability, this paper mainly explores the data exchange problem how to use XML in heterogeneous database system, , and .Net platform have good support to XML and heterogeneous database system, so the combination of XML and.net, can realize data exchange of heterogeneous database system.

This article proposed uses xml and the Hibernate technology based on the B/S structure realizes heterogeneous database dynamic integration plan. This system through the programming interface JDom to implement a Hibernate configuration file automatically generated, using of global data dictionary access to various heterogeneous data sources and the overall database table, and realization of the heterogeneous data sources and automated maintenance of the global data dictionary. The system has a good maintainability, scalability, portability, etc.
