What is denormalization and when would you go for it?

Answer Posted / niraj kumar

Industrial experience---->

Denormalization or Normalization both we use on databse so
that any one can filter as well as retrive the data from
the tabel easily.
Denormalization - As the name suggest it is a reverse
process of normalization, means we fill some redundant data
in table so that user can retrive easily.
But actualy we use the major functionality of normalization
of higher normal form(BCNF, 4TH NF ,5TH NF, DKNF) in lower
normal form (1st and 2nd) because higher normal forms are
so costly to use, thats why we use denormalization to
reduce the cost of normalization.
