With QPR BizArchitecture Server use QPR Modeling Client uses QPR User Management System for user authentication. System is shared between all of the QPR products. Users are authenticated through the User Management System but the user rights for the QPR Modeling Client models are still saved to the models in the QPR database. For detailed information of QPR User Management System, see the QPR Administrator's Guide. There are also model administrator users who can carry out many operations usually reserved for QPR Modeling Client administrators. These operations are, for example, publishing a model, checking out/replacing a model, modifying user rights of a model, using Metrics links. See the User Administration Dialog section for more detailed information about applying user rights to models.
