Different Views of Database

There are three different views of the database. The views are seen through the schema and the sub-schema of the data.

Logical view of the user of data

          This is a view of the application programmer or user as he wants it. This could be a partial view of the database. For example, the quality control manager and the purchase manager would view the data differently for their use.

The view of database administrator (DBA)

           This is a view of the person who is managing the database through the creation, updating, structuring and ensuring that it is up-to-date. The view of the DBA is a global view.

Physical View

            This is the view of the data actually stored and organized on the physical devices.
