摘要： 用户视图间的依赖关系对于信息资源规划中的数据分析和数据建模有着重要的意义。该文对用户视图间的依赖关系进行了定义和说明，并细分其为数据依赖和操作依赖，在此基础上，对用户视图间的依赖关系进行了度量，提出了依赖度和被依赖度2种度量方法，为规范用户视图提供了依据。

Abstract: Dependency relations among user views are important in data analysis and data modeling in information resource planning(IRP). This paper introduces the definition of user view dependency and divides it into data dependency and operation dependency. Based on that, it measures the user view dependency relation and describes two methods: depending degree and depended degree, which provide a foundation for standardizing user views.
