【Abstract】 In this paper, we describe the basic logical models for OLAP applications, and present different proposals for multidimensional data cubes. We have grouped the work in the field in two categories: commercial tools and academic efforts. We further divide the academic efforts in two subcategories: the relational model extensions and the cube-oriented approaches. Finally, we try to make a comparative analysis of the various efforts.更多还原
