摘要
目前,元数据管理存在这样的问题,各开发商使用不同的元模型来设计自己的数据仓库工具,而且对元数据的描述往往不一致,这样给数据集成带来很大的问题。使用一种基于模型驱动的方式,将元数据描述规范化,并运用基于模型驱动的公共仓库模型CWM(Common Warehouse Metamodel)来实现这一过程。该模型可以充分发挥软件的复用性,使系统有良好的通用性,从而提高系统开发效率。
Nowadays,there are such problems in metadata management that developers design their respective data warehouse tools with different meta-models,whereas their descriptions about meta-data vary from each other.Therefore it brings a lot of trouble in data integration.The article applies an MDA-based method to standardize metadata description and makes use of MDA-based CWM meta-model to realize the process.The model takes full advantage of the reusability of the software to enable the system to bear fine universality so that the system development efficiency is improved.
