Description: Row-level security is a feature that allows restricting access to specific rows in a table based on user permissions. This functionality is crucial in environments where protecting sensitive data is a priority, as it enables different users to access the same table but only the information that pertains to them. In the context of databases, this feature is implemented through policies that define which rows are visible to each user or user group. This not only enhances data security but also optimizes query performance, as users only process the information relevant to them. Row-level security integrates with other database security features, such as authentication and authorization, creating a robust environment for data management. Additionally, it helps comply with data protection regulations, such as GDPR, by ensuring that personal information is not accessible to unauthorized individuals. In summary, row-level security is an essential tool for data management in multi-user environments, ensuring that information is handled securely and efficiently.
