I was just searching for the best explanations and reasons to build a OLAP Cube from Relational Data. Is that all about performance and query optimization?
It will be great if you can give links or point out best explanations and reasons for building a cube, as we can do all the things from relational database that we can do from cube and cube is faster to show results.Is there any other explanation or reasons?
There are many reasons why you should use a cube for analytical proccessing.
I hope this helps.
