摘要 分析装备体系数据仓库使用的基本特点,提出装备体系数据仓库的总体框架和数据集市。建立以基础数据维、元数据维和模型维为基础的三维数据模型立方体结构,给出其结构之间的逻辑关系并进行形式化描述,提出一种"阶梯式"的元数据管理模式。通过一个模型运行的示例介绍模型计算的实现方法。 By analyzing the basic characteristics of use of Data Warehouse of Armament System of Systems(DWASS), this paper gives a new framework and marts of DWASS. It puts forward a new three-dimensions Data Structure(3D-DS), which includes the dimension of basic data, the dimension of metadata and the dimension of model, and the relationships among 3D-DS are revealed. It formalizes the 3D-DS. A new way called "ladder method" is proposed to manage metadata in DW. An example is introduced to explain the function of 3D-DS works in DW environment.
