Edit displayname in database

is it safe to change the displayname of an user directly in the mysql database? I mean the displayname in the oc_users table which is the full name of the user.
Are there any relations between the displayname and other parts in the database? I'm asking only for a core installation without any 3rd party apps.


Why not use the Provisioning API?

Thanks. I'm going to use the API but I wonder whether there is any connection in the database.

Database manipulation should always be avoided, there is always risk involved. Thats why we are implemeting APIs for all the good stuff. Thanks for using the Provisioning API.
