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