Answer / gireesh
Normalization is a process in database design which groups
data into various tables which are then crosslinked by a
particular field. In a properly normalized database, there
will be only one field in one table for a particular piece
of data, eliminating possibility for conflicts. Breaking the
database up into numerous smaller tables, and eliminating
redundancies, eases management and enhances efficiency.
