Answer from AI
In the context of databases, a "View" is a virtual table that is formed based on the result of a query to one or more tables. A view does not store data physically but displays it dynamically when accessed.
Main advantages of using a View:
- Simplifies complex queries, providing a convenient interface for users.
- Enhances security — access to certain columns or rows can be restricted through views.
- Centralizes 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.
