ABSTRACT
This paper briely traces the evolution of information system architectures from mainframe-connected terminals to distributed multi-tier architectures. It presents the challenges facing developers of multi-tier information systems in providing effective consistent data policy enforcement, such as access control in these architectures. Finally, it introduces "Mobile Policy" (MoP) as a potential solution and presents a framework for using mobile policy in the business logic tier of multi-tier information systems.
