异构数据库集成中间件的设计与实现

Design and Realization for Heterogeneous Database Integration Middleware

随着信息产业和通信技术的发展,企业在信息化建设过程中构建起多个异构的信息系统。为了解决网络环境中异构数据库的数据集成和共享问题,提出了一种基于XML和数据库连接池的异构数据库集成中间件模型。在此模型中设计了翻译器、分发器、集成器,分别用于数据的格式转换、分解和合并,并对模型实现过程中的关键技术给出了详细描述。为了进一步提高数据库访问效率,引入了数据库连接池技术,实现了分布式异构数据库的透明访问和联合查询。

With the development of information industry and communications technology, enterprises have built multiple heterogeneous information systems in the process of building information. In order to resolve data integration and sharing among heterogeneous databases in the network, this paper, based on XML and database connection pool, provides a middleware model for heterogeneous database integration. In this model, designed interpreter, dispatcher, integrator used for data format change, data decomposition and data combination, and de- scribes the important technologies of realizing process. To further enhance the efficiency of database access, this paper introduces the database connection pool technology, this model realizes the transparent access and joint inquiry for distributed heterogeneous database.
