一种数据仓库互操作框架的设计

为了节省网络带宽,加快各数据仓库之间互相访问速度,在Web服务器基础上构造了一个支持和应用移动Agent的数据仓库互操作框架.该框架采用中间件技术,能够在有限的网络资源下,避免大量数据的网络传输,提高查询效率,提高在网络连接断续和不稳定情况下互操作的可靠性,便于升级和维护,具有良好的伸缩性和适应性.

A Design of Framework for Data Warehouses Interoperability

In order to save network bandwidth and quicken the speed of access between data warehouses,we construct a framework for data warehouses interoperability which supports mobile agent on existing web infrastructure, The framework adopts technology of middleware.Under the limited network resource,the framework can avoids transferring a mount of data in network,boosts query efficiency, impoves reliability of interoperability when network intermittence and uncertainty.The framework is easy to upgrade and maintenance.It has good retractility and flexibility.
