摘要
针对军事交通运输保障装备管理(Military Transportation Indemnificatory Equipment Management,MTIEM)数据结构复杂、层级较多的特点,从多维数据模型相关理论入手,以ER模型为基础,论述层次主键模型(Hierarchy Principal Key Model,HPKM)构建方法,并将其向多维模型转换,提出其多维数据模型构建方法,为联机分析处理提供支撑。
Aiming at the complete data structure and multi-levels of military transportation indemnificatory equipment manage(MTIEM),based on the theory of multidimensional data model and ER model,introduce the approach of building the hierarchic primary key model(HPKM) and the method of the transformation from HPKM to multidimensional model.It will support to the on-line analytical processing(OLAP).
