7. Department of Computer Science Spring 2013: April 3 CS 157B: Database Management Systems II © R. Mak 7 Project #4  Dimensional modeling and OLAP  Implement a star schema suitable for OLAP operations. Use MySQL. Use Cognos for inspiration and as an example.  Fact table Tall and skinny, normalized. Choose your measure and grain.  Dimension tables At least three, can be unnormalized. Each dimension should be hierarchical.  Populate your tables Use data from Cognos or create your own data.

8. Department of Computer Science Spring 2013: April 3 CS 157B: Database Management Systems II © R. Mak 8 Project #4  OLAP operations with two-dimensional reports Choose dimensions  Generate reports that show combinations of two dimensions. Drill up and drill down  Generate base report, drill up report, drill down report Slice and dice  Generate base report, slice report, dice report Pivot  Generate two reports, one a pivot of the other  Generate reports with SQL scripts or with Java programs (Hibernate or JDBC) Do not have to be interactive. No GUI required.
