Abstract

In a multilevel security database there are multiple beliefs about a given real world object. The ability of a database model to accommodate multiple beliefs is termed polyinstantiation in the multilevel security literature. In thi paper we remark that in an abstract sense polyinstantiation is a priori present in all models for temporal and spatial datbass. In particular we investigate the applicability of the paramtric models for temporal data to query multilevel security data nd, as a case study, compare it to model for multilevel scurity given by Winslett, Smith, and Qian.
