In RDBMS all the data is stored in tables.

It is ensured that all the data is stored in the form of rows and columns.

The concept of primary key is used for the unique identification of each row.

With the help of foreign key, data can be extracted by joining two different tables.

With the help of validation rules, we can define which type of data can be entered in which column like: number, text, date etc.

With the help of normalization process, data can be organized in database without redundancy.

By creating an index, you can increase the speed of data retrieving.

With the help of virtual table, we can simplify the queries.
