摘要
针对建立数据仓库时存在的系统需求不断变化、语义断层以及数据仓库改动难、代价大等问题,文中提出一种N层数据仓库体系结构模型,以及基于原型法的数据仓库建立方法。文中给出了运用面向对象原型法建立N层数据仓库的关键技术,并阐述了利用原型法进行N层数据仓库开发的优点。该设计思想在PLM产品生命周期管理系统中使用并取得了较好的决策支持效果。
Due to the problems of constantly changing requirements, semantic faults and high expenses met as setting up or changing the data warehouse,puts forward an N- layer data warehouse architecture model,and one method for developing data warehouse based on the thought of object - oriented prototyping. The key technologies for establishing an N - layer data warehouse with prototyping method are given and the advantages of this method are also presented in this paper. This design has been used in PLM product life cycle managment system and made a better result of decision support.
