基于全局目标视图分解与重写算法的数据交换中间件的研究与实现

A DATA EXCHANGE MIDDLEWARE’s REASEARCH and REALIZATION BASED ON GLOBAL TARGET VIEW's DECOMPOSITION and RECOMPOSITION ALGORITHM

    摘要
  • 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．

     

    Abstract: Benefiting from the data warehouse online maintenance technology， user's demand 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 single data source. Here data share and exchange are achieved by materializing those views.
