Some Aspects of Multidimensional Data Modelling and OLAP
We will discuss some of the problems that the OLAP providers are
facing. In particular this involves data and metadata modelling
issues, sparsity issues, formula dependency analysis, appropriate
index structures, etc. The purpose of the talk is to identify
currently unresolved problems and discuss their possible solutions.
