Abstract: 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.
