Normalization:
normalization is used to reduce the repetition..
for example if a table contains a column repeating same datatype and for same purpose..
look at simple example a item purchased of a customer may contain many which also include separate prices so instead of creating repeated column for each item and price.. one table is created with one column for item name and one for column name.. then relationship(one to many) can be created and records in item table can be connected with cstomer table which includes order no as primary key..
