what is the difference between first normal form & second
normal form?

Answer Posted / imran khan

First normal form, sets the very basic rules for an
organized database i.e. Eliminate duplicative columns.
Create separate tables for each group of related data and
identify the row with a unique column i.e the primary key.

Second normal form further removes the duplicate data:

i.e. Meet the requirements of the first form of
normalalization. Create relationships between new tables
through foreign keys.
