The multiplatform runtime uses JDBC driver for database connection purpose.
This window allows the user to select required driver and enter connection properties: connect string (also known as URL), user name (login) and password.

Please refer to your driver manual for detailed information about connection string for your database.
The login (user name) and password are optional and depend on the driver and connect string.

The connection information is optional if:

1. "File only" mode specified at the output properties window
2. No prologue and epilogues scripts at the project and rule level are present
3. No database-related fill methods like $Table or $Query are used in the data generation options.
