Is it normaliztion will reduces performence?
I heard database performance will be down by using normalization from my friend.
I known only advatages tillnow , by using it we can reduce the redundency of data in
database.Even codd also specified abt normalization power in his 12 rules.however i didn't
get disadvatages of normalization.
can anybody give disadvages of normalization and also why it reduces
performance.
