You will need to have installed one of the supported databases, mySQL, SQL Server or Oracle as the first step. Then create a user account for the Commander application to use.
This user must have permissions to create tables, indexes, functions and views.
To create your database for the first time have a look at this video

For each new version of Commander4j you need to update the database which is shown in the video below.
For upgrades always take a backup of your database BEFORE the upgrade is started.
