摘要： 公共仓库元模型为构造数据仓库领域的元数据提供了统一的标准。该文对元数据交换环境作了具体分析,提出了一种基于约束模型的方法来约束CWM中的元数据,并通过一个实例说明该方法可使CWM元数据满足各种交换环境。

Abstract: CWM (common warehouse metamodel) provides a standard for constructing metadata in data warehouse domain. This article analyses the metadata interchanging context firstly, then comes up with a model-constraining based method to constrain the CWM metadata, followed by an example to illustrate the effect of this method.
