摘　　要：随着网络技术的发展,信息的共享和交换显得越来越重要。针对目前网络中信息的异构性、多样性、分布性等特点,提出了一种基于Web Services的异构信息集成方案。该方案中,主要采用XML技术对各种源信息进行包装,形成了一个虚拟数据库,从而实现了异构数据源的共享。然后将信息注册在信息注册中心,信息请求方获得XML格式的信息后,使用XML解析器对其解析。该方案有效解决了"信息孤岛"问题。With development of Interact technology., the need for sharing and exchanging of information is becoming more and more important currently. In the paper,a heterogeneous information integration schema built on Web Service is proposed, which can accommodate to the heterogeneous, disperse and various information in present Internet. The scheme uses XML to encapsulate the information which will be changed in deferent systems, so the heterogeneous data source can be combined to form a virtual database then registries it to the information registry center. After the information requesters receiving the XML information, analyze it with XML parser. A scheme based on Web Services can effcctivdy to solve the problem of ＂information island＂.
