摘要
目的解决装备保障数据仓库实施中数据建模问题。方法总结近年来多维数据模型的构建方法,对基于本体的多维数据模型构建方法进行优化,提出适于装备保障数据多维模型构建的"本体-层次"建模方法。结果该方法的运用,能够在庞大的装备保障体系中,较为便捷地提取数据模型的维度与指标,简化了多维数据模型的构建过程。结论为装备保障数据仓库的实施提供了有力支持。
Objective To solve the issue of the construction of multidimensional data model in the implementation of e-quipment support data warehouse. Methods This paper summarized multidimensional data modeling methods in recent years, optimized the ontology-based multidimensional data modeling method and put forward a new method of establishing multidimensional data model-＂ ontology-AHP＂ construction method. Results This method conveniently extracted the dimen-sion and indexes for the data model from the large equipment support system and simplified the construction process of mul-tidimensional data modeling. Conclusion It provided strong support for the implementation of equipment support data ware-house.
