What experience do you have with using views in relational databases?

Views in relational databases are virtual tables that are formed based on the result of an SQL query. They do not store data physically but display it dynamically upon access.

Experience with views includes:

• Simplifying complex queries: you can create a view by joining multiple tables and use it as a regular table.
• Improving readability and reusability of code.
• Access restriction: providing users access only to certain columns or rows through a view.
• Optimization: some DBMSs can cache results or optimize queries using views.

For example, in Python using SQLAlchemy, you can interact with views just like tables, which simplifies data handling.
