As said by instructor we have to follow the procedure of all 5 five techniques (if required) not only pre-joining

1. Collapsing tables

2. Pre-joining

3. Splitting tables

4. Adding redundant columns

5. Derived attributes

it's not necessary to apply all the techniques.

Dear @Anmol Maha Please share your column sequence............
