this comes in normalisation
nomalisation theory is based on the observation that relations with certain properties are more effective in inserting, updating and deleting data than other sets of relations containing the same data.
normalisation is a multi step process begining with an un normalized relation

there are three type of normal forms
First normal form ( 1NF)
second normal form (2NF)
third normal form (3NF)

To defeat the anomalies!
btw lich, there is more: BCNF, 4NF, 5NF, and 6NF (in concordance with C.J. Date).
Happy normalizations (as Nixon and Codd didn't say)!
