分布异构环境下的数据集成技术研究

Researches on Technology of Data Integration Under Distributed Heterogeneous Environment

目前,企业普遍存在"信息孤岛"林立、数据断层的局面,造成企业信息化的程度难以满足当今日益激烈的市场竞争。为了解决企业的数据集成问题,对目前常用数据集成方法进行了分析,给出了基于Web服务的数据集成方案。该方案具有松散耦合、跨平台、与编程语言无关、可穿越防火墙、可扩展性好等优点,可以在保留企业原有IT投资的基础上,完成分布、自治、异构数据源的集成,实现信息共享,在低风险、低成本的前提下提高企业的现代化管理水平和办事效率。

At present, there is a ubiquity of isolated information islands and data gap among the different departments in enterprises, which leads to the fact that enterprises＂ computerization can not meet the demand of increasingly severe competionin the market. In order to promote data integration, this paper analyses the present ways of data integration, and proposes a data integration solution which is based on web service. The advantages of this solution include loose Combining, cross-platform, independence of program language, ability to get through firewalls, excellent extensibility. This solution can integrate distributed, autonomous and heterogeneous data sources, and help the different enterprises improve their modem cost. departments share the same information, and enable management efficiency on the premise of less risk and the low
