The QLM database includes a field called UserData1 which can be used to store any information of your choice and associate it to a license.
UserData1 in the main License Keys table
The UserData1 field in the main license keys table can be used to associate any custom data of your choice to a license key.
We recommend that you store data in a structured form such as in XML or Json so that you can easily store additional information in the future as your requirements evolve.
Additionally, most of the QLM HTTP APIs allow passing the user data as via the is_userdata1 URL argument.
UserData1 in the Activation Log table
For license keys that allow multiple activations (number of activations > 1), you can also store your own custom data for each activation of a license. Activation information is stored in a separate table called Activation Log.
We recommend that you store data in a structured form such as in XML or Json so that you can easily store additional information in the future as your requirements evolve.
