More specifically, authorization policies are expressed in an SQL-like language which can be easily rewritten into query sentences for execution. In addition, the architecture supports dynamic integration and execution of multiple access control policies from disparate enterprise resources. Finally, a prototype implementation of the dynamic business process management architecture is described
