| Abstract: | In this paper,we propose a new security database relational model,including a multilevel security model and enhanced foreign key referential function.We extend the Sandhu's MLR model with new semantics which represents the real world more rationally and practically.And the enhanced foreign key referential function increases the ability of modelling. |
