JDBC (Java Database Connectivity) drivers allow Java-based applications to connect to SQL-compliant databases.

DB Navigator includes several JDBC drivers that allow connections to supported databases. You can see the list of all available drivers in the JDBC Drivers preferences page, which you can access by choosing Window > Preferences > Progress Databases > DB Navigator > JDBC Drivers. You can also add other JDBC drivers.
Note: Since JDBC drivers execute SQL statements, you must start databases that can service SQL clients. Also note that for an OpenEdge database, ABL access is required for trigger maintenance. Therefore, define database servers with the client type of Both 4GL and SQL (which is the default).
