In the context of databases, a "View" is a virtual table that is created based on the result of a query on one or more tables. The view does not store data physically but displays it dynamically upon access.
Main advantages of using Views:
- Simplification of complex queries, providing a user-friendly interface.
- Increased security — access to certain columns or rows can be restricted through views.
- Centralization of data retrieval logic.
Example of creating a View in SQL:
CREATE VIEW active_users AS
SELECT id, username, email
FROM users
WHERE status = 'active';
Now you can access active_users as if it were a regular table.
