JDBC:

To connect to a database via JDBC, a driver file specific to a database type must be present on a user's machine. RazorSQL ships with JDBC drivers for several databases. RazorSQL also allows users to obtain JDBC drivers manually and use those drivers to communicate with a database.

JDBC drivers can be obtained, usually free of charge, from the database vendor' web site. After obtaining the drivers, connections to the database can be configured using the RazorSQL connection wizard.
