GL HUTCHINSON · Defense Technical Information Center (DTIC) · 1991
Pollyanna is a simple secure DBMS which utilizes polyinstantiation. It has been designed and implemented to illustrate the problems which may be encountered when applications are built on top of a polyinstantiating DBMS. The implementation comprises of a front end to a standard commercial RDBMS. The front end performs query modification and result filtering to achieve security. This document describes Pollyanna, the front end software and some of the problems which arose during the design of the system. (Author)
