Phase 5. Custom Project

Describe your custom OLAP reporting work.

Basis and Data

  2. Dice. What two dimensions you chose for your dice and why
  3. Drilldown. What level of drilldown you implemented and what it revealed

  7. Custom Reporting. What custom operation or query you added beyond the example

Findings

Describe what your OLAP analysis revealed.

Include:

  1. Slice. What your slice showed about that dimension
  2. Dice. What your dice revealed about the combination of dimensions
  3. Drilldown. What the drilldown exposed that the summary view missed
  4. Rollup. What the rollup revealed at a higher summary level
  5. Results. Any surprising or counterintuitive results

Summary

Summarize your custom reporting work.

Include specifics showcasing your analysis:
