Hybrid OLAP Tools

Online analytical processing (OLAP) tools are now using visual presentations like charts, maps and diagrams to help users detect data patterns that help in the decision-making process. A few vendors have come out with innovative implementations of the OLAP technology.

  • Tableau from Tableau Software generates tables from standard structured OLAP and relational data sources, has an interactive display, and can hold embedded charts with multidimensional data views within cells.
  • Kheops Technologies' JMap Spatial OLAP extension presents a multidimensional view of data through interactive maps, tables and diagrams. It also offers Web map navigation and manipulation with a modular architecture.
  • Text OLAP that is a part of Megaputer's PolyAnalyst suite of data and text mining tools delivers an interactive, structured analysis of text documents. The difference between conventional text mining is evident in the use of extracted terms and concepts as dimensions. Entities are displayed in the matrix form with linked charts and color-coded extracts from the reference documents.
