【摘要】 随着计算机技术的发展,很多企业内部实现了信息的计算机管理,积累了大量的数据。这些数据存在异构现象,相互之间难以集成和共享。传统的数据集成方法已经不能适应企业获取信息的需求,迫切需要一种新的数据集成系统。在XML技术基础上,提出一种基于本体的异构数据集成系统,用来解决数据源之间的语义异构问题。给出一种基于本体的异构数据集成的系统结构,对关键技术问题进行了研究,指出了系统今后研究的方向。更多还原

【Abstract】 With the deveplement of computer,many enterprises finishs the computer mangment of information and accumulates a lot of information.There exites heterogeneous phenomenon in datas.It’s hard to integration and share.The traditional data integration doesn’t fit the demand that the enterprise obtain the information.So,new data integration is expected to appear.In order to resolve the semantic heterogeneity of data sources,a kind of the heterogeneous data integration system based on XML is proposed.The kind structure of system is designed.The key technologies are discussed.And the research to the system for the future is given.更多还原
