【摘要】 针对企业信息化建设中出现的异构数据源问题,设计了一种跨平台、语言无关、松耦合、可扩展的异构数据库统一平台系统模型。整个设计基于XML技术和Web Services技术。本文研究了集成系统的设计并实现了异构数据源的集成。首先详细介绍了应用的关键技术,采用JTA技术管理分布的子数据源的事务,JTA的二阶段提交协议保证整个系统运行时的事务安全。接着对系统的架构、用户请求解析模块、数据集成与格式化等问题做了详尽全面的分析与设计。最后以一个实例完整展示了异构数据源的集成过程,实现了数据源业务逻辑的封装与热部署,并使用RPC远程调用成功。本课题的研究对缓解目前及未来企业的信息化建设中遇到的问题具有重要的参考价值,对异构数据库系统这一广泛而重要的领域的发展具有一定现实意义。更多还原

【Abstract】 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.更多还原
