Views: A view is a virtual table created from the result of a SQL query. It doesn’t store data on its own; instead, it presents data from one or more underlying tables in a structured manner. Views allow you to simplify complex queries, control data access, and provide an abstraction layer for users to interact with the data without exposing the underlying table structure.

Benefits of Views:

• Simplified Queries: Views can encapsulate complex queries, making it easier for users to retrieve specific data without dealing with intricate SQL syntax.
• Data Security: You can grant different users access to specific views, restricting their access to certain columns or rows in the underlying tables.
• Abstraction: Views provide an abstraction layer that shields users from changes to the underlying table structure. You can modify the table structure without affecting the view’s interface.
• Performance: In some cases, views can help improve query performance by predefining joins and calculations.

CREATE VIEW customer_orders AS
SELECT customers.name, orders.order_date
FROM customers
JOIN orders ON customers.id = orders.customer_id;
