Answer #1

`Hey,

Note: If you have any queries related the answer please do comment. I would be very happy to resolve all your queries.

It is a generalized non-DBMS specific design. Much easier to change during design. Changing a relationship after creation would be much more difficult because data must be migrated to the new structure. SQL statements will need to be changed, forms and reports will need to be altered.

Kindly revert for any queries

Thanks.
