Efficient data structures are generated to enforce permissions on a multi-dimensional representation in a performance management application. A model site is generated having at least one model with at least one dimension. User permissions and group permissions are set for the model. The user permission and the group permissions are deployed to a relational database. A collective user permission table is generated based on the user permissions and the group permissions. Thus, an end user may receive permissions associated with a model and permissions associated with particular dimensions of a model without an inefficient consumption of resources.
