摘　　要：介绍数据集成中间件技术的基本概念与体系结构,分析现有数据库连接池的工作原理和工作机制。在得出现有连接池局限性的基础上,设计出动态连接池体系结构。通过采用基于中间数据库和变化日志表的异构数据复制模式和以虚拟订阅表的方式构建的全局查询模式,将动态连接池中间件扩展成为数据集成中间件,从而有效解决异构数据库间的数据共享与交换问题。It introduces the basic concept and architecture of data integration middleware and analyzes the working method and working theory of present database connection pool. Based on the elicited disadvantages of present connection pool, the system structure of dynamic database connection pool was designed. Through adopting a kind of heterogeneous data replication mode based on middleware database and changing log file and .global query mode built with virtual subscription table, dynamic database pool was extended to a sort of data integration middleware of dynamic database connection pool. The model was used to resolve the data share and exchange problem effectively in heterogeneous database.
