IMPLEMENTATION OF NORMALIZATION

Ex No:12

AIM:Create a table called customer_order and implement the concept of

Normalization.

PROCEDURES:

1NF Eliminates repeating groups-make a separate table for each set of related

attributes, and give each table a primary key.2NF Eliminates redundant data-if an attribute depends on only part of a multi valued

key, remove it to separate table.

3NF Eliminates columns not dependent on key-if an attribute do not contribute to a

description of the key, remove them to a separate table.


41/53




BCNF Boyce Codd Normal form If there are non-trivial dependencies between

candidate key attributes, separate them out into distinct tables.

4NF Isolate Independent Multiple Relationships No table may contain two or

more 1:n or n:m relationships that are not directly related.

5NF Isolate Semantically Related Multiple Relationships There may be practical

constrains on information that justify separating logically related many-to- many

relationships.

ONF Optimal Normal Form- a model limited to only simple (elemental) Facts, as

expressed in Object Role Model notation.

DKNF Domain-key Normal Form a model free from all modificationanomalies.

ALGORITHM:

Table description: customer_order

Column_name Data_type Constraint

Cust_order_date Date Not null

Cust_id Number(6) Not null
