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 the development of network technology, it is more and more important to share and exchange information. Aiming at the heterogeneity, diversity and distribution of information in the current network, this paper proposes a heterogeneous information integration scheme based on Web Services. In this scheme, all kinds of source information are mainly packed by XML technology to form a virtual database, so as to realize the sharing of heterogeneous data sources. Then the information is registered in the information registration center, the information requestor obtains the information in XML format and parses it using the XML parser. The program effectively solved the “information island” problem.
