Hi @kamalhinduja, 

There's a great article here: https://docs.databricks.com/aws/en/delta/best-practices 

If you look down the left-hand side navigation pane on the link above, you'll find a bunch of useful articles surrounding the Delta Lake and Delta Tables. 

It might also be worth doing some research on Data Modelling in a Data Lakehouse 😎.

Hopefully that's useful. 

All the best
BS
