2)In data warehouse technology, a multiple dimensional view can be implemented by a relational
database technique (ROLAP ), or by a multidimensional database technique (MOLAP ), or by
a hybrid database technique (HOLAP). Give answer for the following:
i. Briefly describe each implementation technique.
ii. For each technique, explain how each of the following functions may be
implemented: (any two parts)
1. The generation of a data warehouse (including aggregation)
2. Roll-up
3. Drill-down
4. Incremental updating
iii. Which implementation techniques do you prefer, and why?
