Figure :- 10.1 Repeating groups example For in the above example city1 and city2 are repeating.In order this table to be in First normal form you have to modify the table structure as follows.Also not that the Customer Name is now broken down to first name and last name (First normal form data should be broken down to smallest unit). Figure :- 10.2 Customer table normalized to first normal form Second Normal form The second normal form states that each field in a multiple field primary keytable must be directly related to the entire primary key. Or in other words,each non-key field should be a fact about all the fields in the primary key. In the above table of customer , city is not linked to any primary field. Figure :- 10.3 Normalized customer table. 194
Figure :- 10.4 City is now shifted to a different master table. That takes our database to a second normal form. Third normal form A non-key field should not depend on other Non-key field.The field "Total" is dependent on "Unit price" and "qty". Figure :- 10.5 Fill third normal form So now the "Total" field is removed and is multiplication of Unit price * Qty. Note :- Fourth and Fifth normal form is left as a home work to users. (B)What is denormalization ? Denormalization is the process of putting one fact in numerous places (its vice-versa of normalization).Only one valid reason exists for denormalizing a relational design - to enhance performance.The sacrifice to performance is that you increase redundancy in database. (B)What is a candidate key ? A table may have more than one combination of columns that could uniquely identify the rows in a table; each combination is a candidate key. During database design you can pick up one of the candidate keys to be the primary key. For example, in the supplier table 195
