Algèbre OLAP et langage graphique
摘要：
本文研究了基于多维模型的联机分析处理系统。我们提供的概念模型，表示数据通过星座（多事实）组成的几个多层次的维度。在此模型中，数据通过多维表显示。我们定义了一个处理这些表的查询代数。这种面向用户的代数是由一个封闭的核心OLAP运算符尽快高级运算符专用于复杂的分析。最后，我们指定了一个图形化的OLAP语言的基础上，这个代数。这种语言便于决策者进行分析。
英文摘要：
This article deals with OLAP systems based on multidimensional model. The conceptual model we provide, represents data through a constellation (multi-facts) composed of several multi-hierarchy dimensions. In this model, data are displayed through multidimensional tables. We define a query algebra handling these tables. This user oriented algebra is composed of a closure core of OLAP operators as soon as advanced operators dedicated to complex analysis. Finally, we specify a graphical OLAP language based on this algebra. This language facilitates analyses of decision makers.
