CWM多维元模型中键的定义方法

A Method for Defining Key of CWM Multidimensional Metamodel

在CWM的基础上,分析了在多维实体资源中增加键的一种机制,同时依靠CWM的扩展机制,给出了一种为多维实体资源产生键的技术,从而得到一套在多维实体资源中键自动产生并加入的方法。给出了该方法的元模型,为多维资源的建模提供一个框架,并且利用XMI给出了元模型的形式化表示,最后分析了元模型的一个具体使用实例。

In this paper, a mechanism of adding key to multidimensional entity is analyzed on the foundation of CWM. It presents a technology of generating key in the multidimensional entity resource by CWM extension mechanism. A method of auto-generation and auto-add key in multidimensional entity resource is obtained. A metamodel of this method is given, it can provide a framework for modeling multidimensional resource. Moreover, the formal expression in XMI of the metamodel is offered. Finally, the example of this metamodel is presented.
