Abstract :
The Schematic Protection Model (SPM) allows us to specify the protection structure of an object-oriented database and provides an algorithm to reason about the transmission of privileges. In this paper, we extend the SPM model to support multiple access policies, by introducing the concept of groups and the negation of authorisation
