Data Modeling Method of Armament System Based on Data Warehouse

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.
