Concept Description vs. Cube-Based OLAP

  • Similarity:
    • Data generalization
    • Presentation of data summarization at multiple levels of abstraction
    • Interactive drilling, pivoting, slicing and dicing
  • Differences:
    • OLAP has systematic preprocessing, query independent, and can drill down to rather low level
    • AOI has automated desired level allocation, and may perform dimension relevance analysis/ranking when there are many relevant dimensions
    • AOI works on the data which are not in relational forms
