View Based Security
View Based Security is a database security model that restricts user access to data by exposing only specific subsets of data through database views, rather than granting direct access to underlying tables. It works by creating predefined queries (views) that filter or transform data, and then granting users permission to query these views instead of the base tables. This approach provides a layer of abstraction that enforces data security and privacy at the database level.
Developers should implement View Based Security when building applications that require fine-grained data access control, such as multi-tenant systems, healthcare applications with HIPAA compliance, or financial systems with role-based data segregation. It is particularly useful in scenarios where different user roles (e.g., managers, employees, customers) need access to overlapping but distinct data sets, as it centralizes security logic in the database and reduces the risk of accidental data exposure in application code.
