【摘要】 共享数据库在数据集成中用的比较多,但是它本身也有一些局限性,比如说保密数据容易泄露,数据传输的速度不够快等。分析比较了目前已有的基于共享数据库的集成方案以及基于数据交换中心的数据交换方案的优劣性,并在比较的基础上提出了一种新的将数据交换中心加到共享数据库体系中的改进型数据集成方案,其中数据交换中心采用了JMS数据交换技术。更多还原

【Abstract】 Shared database is common used for data integration,but it also has its own limitation such as easy leaking of secret data and slow rate of data transferring etc.A comparison and analysis between the solution of data integration is made based on shared database and the solution of data exchange based on center of data exchange.An improved solution of data integration is presented.The solution adds the center of data exchange to the architecture of shared database to improve the solution of data integration,in which the JMS tech-nology is used for the center of data exchange.更多还原
