Role Based Access Control With Database Level And Query Level Permissions

via “authentication and access control with role-based permissions”

MariaDB server is a community developed fork of MySQL server. Started by core members of the original MySQL team, MariaDB actively works with outside developers to deliver the most featureful, stable, and sanely licensed open SQL server in the industry.

Unique: Implements a multi-level privilege system (global, database, table, column, routine) with role-based access control and pluggable authentication methods. Uses an in-memory privilege cache (acl_cache) for performance, with cache invalidation on privilege changes.

vs others: More granular than PostgreSQL's role system (column-level privileges); simpler than Oracle's fine-grained access control but less flexible
