What is Databases?

Power BI connects to relational and analytical databases such as SQL Server, PostgreSQL, MySQL, and Oracle through native connectors. These connectors typically support both import and DirectQuery modes, letting the choice depend on data volume and refresh needs. Database connections often require credentials and, for on-premises systems, a gateway to reach the data securely.
