摘要
1 引言
多数据源信息集成系统是近年来数据库界和人工智能界研究的热点.在复杂的数据库应用环境中,如CIMS、DSS、IQ&AS、DW等,各种数据往往分布在多个不同源系统上,如数据库系统、文件系统,以及Web系统.
With the development of Internet ,network data increase drastically,and the application requirements according to the network information are becoming more and more,thus traditional methods of browsing by text linking and keyword searching can't satisfy more complex applications. Multiple Data Source Integration System is to set up an environment so that all sorts of sources can cooperate to provide better services. This paper first introduces technological background of multiple data source integration system,then gives the key technology in constructing such a system,and analyzes probable deficiencies in current systems,at last brings forward the future work.
