Answer 2

Answer:

If a view is used to only look at table data. The view is called Read- only view is the correct answer.

Step-by-step explanation:

A view is a virtual or logical table that allows you to view or edit parts of a table. To minimize redundant data, Oracle allows the creation of objects called VIEWs.

A view is associated with a SELECT set. The underlying table of the view is mentioned in the FROM clause of the SELECT statement.

• Some views are used only for viewing table data. You can use other views to insert, update, and delete table data and display data.
• When a view is used to display table data only, it is called a read-only view.
• Views that are used to display, insert, update, and delete table data are called updatable views.

Views are created for the following reasons:

• If you need data security.
• When data redundancy must be minimized while maintaining data security

View type:

• Read-only view: Allows only SELECT operations.
• Updatable view: Allows both SELECT, INSERT, UPDATE, and DELETE operations.
