基于Web Service的异构数据库的集成

分析了现有异构数据源的数据集成的方式，为了保持各数据源的自治性和满足数据查询的实时性，提出使用中间件体系结构的集成方案。介绍Web Service分布式计算模型及其特点，提出了一种基于Web Service技术进行异构数据源集成的方法。通过Web Service能将连接在Internet上的异构数据泺构建成一个虚拟的全局数据库，为用户提供透明统一的接口，从而实现异构数据资源的共享和整合。

The Integration of Heterogeneous Web Service-based Database

This paper introduces the existing approaches to integrate heterogeneous data sources, and proposes a middlewarc-based architecture as an integration solution which not only maintains the independency of each data source, but also racers the real--time requirement of queries. Based on the distributed computing model of Web scrvicc, this architecture builds a virtual global database from the heterogeneous data source in Internet. This database provides an open and standardized interface and realizes the integration and sharing of heterogeneous data sources.
