Answer / ajeet khari
normalization is organizing data efficiently into database...
main thing is 1.elimination of redundant data,2. data
dependencies..
1NF-a table is decomposed into 2D table with no duplicate
column....
2nd NF- should be in 1NF and there should not be any
duplicate row...
3NF- should be in 2NF and contains transitive dependencies
remove that column which are not dependent on PK.
4NF-should be in 3NF and it has no malti valued dependencies.
