This option is helpful in capturing the activities needed, replay the database along with testing, and gauge the change with constant testing. The functional part and the performance part both are optimized using this option.

The OLAP cubes work with the SQL and make the materialistic view for the partition changes. As like the cube consist of many dimensions the data is connected with the dimensions for the view. The dimension can be one to one relationship or many to one relationship. These cubes are saved in the analytic word space of the database.
