Category: Online Analytical Processing (olap) Wikolap: Integration of Wiki and Olap Systems

Data Warehouse (DW) and OLAP systems are Business Intelligence (BI) technologies intended to support decision-making process by means of on-line and multidimensional analysis of large volume of alphanumeric data (Kimball, 1996). DW models represent data according to the multidimensional model, which organizes warehoused data in dimensions (analysis axes) and facts, described by measures (analys...

On-Line Analytical Processing (OLAP) on Networks

We propose a framework for efficient OLAP on networks with a focus on the most interesting kind, the topological OLAP (called “TOLAP”), which incurs topological changes in the underlying networks. Topological OLAP operations generate new networks from the original ones by rolling up a subset of nodes chosen by certain constraint criteria. The key challenge is to efficiently compute measures for...

Online Analytical Processing (OLAP): A Fast and Effective Data Mining Tool for Gene Expression Databases

Gene expression databases contain a wealth of information, but current data mining tools are limited in their speed and effectiveness in extracting meaningful biological knowledge from them. Online analytical processing (OLAP) can be used as a supplement to cluster analysis for fast and effective data mining of gene expression databases. We used Analysis Services 2000, a product that ships with...
