(Continued from previous topic...)
What Are Views?
A view is a database object that represents the data in one or more tables
in the same structure as a separate table. Here are some basic rules about views:
- Tables store real data.
- Views do not store real data.
- Views must have underlying tables to provide data.
- Each view is based on a single SELECT statement to control what data to collect from tables,
and how data should be represented.
- View's columns can be mapped directly to columns in underlying tables.
- View's columns can be created expressions based multiple columns in underlying tables.
- Views can be used in same way as tables in queries.
