【摘要】 构建装备技术保障数据仓库是适应装备信息化发展的迫切需要。本论文对严重影响建模质量的装备技术保障数据仓库多维概念建模进行了研究,在对概念建模需求分析的基础上,提出了一个语义丰富的概念模型 EMDERM,这个模型使用了一系列新的建模构件,包括事实集、维层集、事实关系集、维层关系集等,使用这个概念模型,我们进行了装备技术保障数据仓库的概念建模实践,实践结果表明该扩展模型在表达复杂维层次和复杂度量时具有良好的效率。更多还原

【Abstract】 To accommodate to the rapid development of materiel informationization, the construction of the materiel technical support data warehouse is more and more urgent. Considering that the multidimensional conceptual modeling plays a key role in modeling quality, this paper discuss the conceptual modeling of the materiel technical support data warehouse. Based on the analysis of the conceptual modeling requirements, we present an extended semantically rich conceptual model called EMDERM. In this model, a set of new modeling constructs are proposed, which consist of fact set, dimensional level set, fact relationship set and dimensional level relationship set. With the help of the extended model, we proceed a conceptual modeling to the materiel technical support data warehouse, furthermore, the modeling practice reveals the modeling efficiency in representing complex hierarchies and measures.更多还原
