What is Normalization? 

What is Normalization? 

Normalization is a database design technique which organizes tables in a manner that reduces redundancy and dependency of data.

It divides larger tables to smaller tables and link them using relationships.

In this tutorial, you will learn-

The inventor of the relational model Edgar Codd proposed the theory of normalization with the introduction of First Normal Form and he continued to extend theory with Second and Third Normal Form. Later he joined with Raymond F. Boyce  to develop the theory of Boyce-Codd Normal Form.

Theory of Data Normalization in Sql is still being developed further. For example there are discussions even on 6th Normal Form. But in most practical applications normalization achieves its best in 3rd Normal Form. The evolution of Normalization theories is illustrated below

1st Normal Form >> 2nd Normal Form >> 3rd Normal Form >>4th Normal Form >>  5th Normal Form >>6th Normal Form

Database Normalization Examples –

Assume a video library maintains a database of movies rented out. Without any normalization all information is stored in one table as shown below.

Further We shall discuss on different normal forms in detailed:

 

 

 

 

 

 

How to delete a record in a table using SQL?

The SQL DELETE Query is used to delete the existing records from a table.

You can use WHERE clause with DELETE query to delete selected rows, otherwise all the records would be deleted.

Syntax:
The basic syntax of DELETE query with WHERE clause is as follows:

DELETE FROM table_name
WHERE [condition];

Example:
Consider the CUSTOMERS table having the following records:
+—-+———-+—–+———–+———-+
| ID | NAME | AGE | ADDRESS | SALARY |
+—-+———-+—–+———–+———-+
| 1 | Ramesh | 32 | Ahmedabad | 2000.00 |
| 2 | Khilan | 25 | Delhi | 1500.00 |
| 3 | kaushik | 23 | Kota | 2000.00 |
| 4 | Chaitali | 25 | Mumbai | 6500.00 |
| 5 | Hardik | 27 | Bhopal | 8500.00 |
| 6 | Komal | 22 | MP | 4500.00 |
| 7 | Muffy | 24 | Indore | 10000.00 |

Following is an example, which would DELETE a customer, whose ID is 6:

DELETE FROM CUSTOMERS
WHERE ID = 6;

If you want to DELETE all the records from CUSTOMERS table, you do not need to use WHERE clause and DELETE query would be as follows:

DELETE FROM CUSTOMERS;
