| 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.

| 关 键 词： | 全局目标视图 局部目标视图 数据交换 |

| Abstract: | 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. |

| Keywords: | global target view local target view data exchange |
