Regular View
A Regular View is a database object in SQL-based systems that stores a pre-defined query as a virtual table, allowing users to retrieve data from one or more underlying tables without storing the data itself. It simplifies complex queries, enhances security by restricting direct table access, and improves performance by abstracting data retrieval logic. Views are read-only by default in many database systems, but some support updatable views with certain restrictions.
Developers should use Regular Views when they need to simplify frequent complex queries, enforce data security by exposing only specific columns or rows to users, or abstract underlying table structures for application logic. They are particularly useful in scenarios like reporting, data aggregation, and providing controlled access in multi-user environments, as they reduce code duplication and maintain consistency across applications.
