What is meant by User views?
The term "user views" refers to virtual tables or views created in databases to provide a user-specific perspective on the data. These views (also known as Views) extract and display data from one or more base tables without the need to store additional physical copies of the data. They offer a customized view of the data tailored to the needs of individual users and help avoid redundancy and inconsistencies.
