摘要
借鉴数据仓库在线维护技术思想,提出利用全局目标视图来表达部门用户对数据共享或交换的需求;然后通过全局目标视图分解与重写算法,将全局目标视图分解为仅仅与单个底层数据源相关的局部目标视图,通过对它们的实化来达到企业各部门之间数据共享与交换的目的.
Benefiting from the data warehouse online maintenance technology, user＇s demands on data share and exchange were expressed based on global target view. The global target view＇s decomposition and re -composition algorithm to decompose global target view into local target view were proposed, which merely related with a single data source. Here data share and exchange are achieved by materializing those views.
