Research And Implementation Of A Unified Platform For Heterogeneous Database

Aimed at the problems that informatization of enterprises,this paper designs a mode which in favor of cross-platform,language-independent,loosely coupled and scalable Unified platform for heterogeneous database systems.This design is based on xml and web services technologyThis paper researches the design of integrated system and realization of heterogeneous date source integrating.In the beginning, this paper provides a detailed introduction on the key technologies of this application,JTA manages the distributed transactions of child data sources, the two-phase commit protocol to ensures that the entire system is running the affairs of security.It has made a detailed and comprehensive analysis and design for the system architecture,user request analysis module,date integration and formatting.In the end,an example shows the complete integration process of heterogeneous date source,achieves packaging and hot deploying the bussness logic of date source.Fanally successfully using RPC calls it remotely.The research projects to alleviate current and future enterprise information construction problems have important economic value, heterogeneous database systems this extensive and important developments in the field of great significance.
