军用航空发动机宏观管理数据仓库多维建模研究

A Study on Military Aero-engine Macro-management Data Warehouse Multidimensional Modeling

多维建模在数据仓库建立过程中处于重要地位,由于航空发动机宏观管理的复杂性,目前还没有一种多维模型能够很好地捕获其中包含的复杂语义;结合实体关联模型(ER)语义捕获能力强的特点以及星型数据模式的简洁性,通过按用户的多维数据分析要求特化ER模型的构件集;得到扩展多维ER模型,对航空发动机宏观管理数据仓库多维建模进行了尝试.

Conceptual model plays an important role in the process of building data warehousing. But here is still not a multidimensional model that can capture the complex semantics of aero engine macro management fully. For ER model's property of capturing complex semantics and Star scheme's property of concision, this paper purposed a new multidimensional data model to model the complex domain of aero engine macro management during data warehousing by specializing the constructs set of ER model in user's multidimensional data analyzing way.
