Description: Views in SQL are database objects that represent a stored query. They can be considered as virtual tables, as they do not store data themselves but dynamically generate results from underlying tables each time they are queried. Views allow for simplifying the complexity of queries, providing a way to encapsulate business logic and facilitate access to specific data. Additionally, they offer a layer of security, as they can restrict the data that users can see or manipulate. Views can be used to combine data from multiple tables, perform calculations, or aggregate information, making them versatile tools in database management. Their use is common in relational database systems, where there is a need to present information clearly and structured, without exposing the complexity of the underlying database.
