Some Aspects of Multidimensional Data Modelling and OLAP

Alex Russakovskii


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.
