A design approach for a secure multilevel object-oriented database system is proposed by which a multilevel object-oriented system can be implemented on a conventional mandatory security kernel. Each object is assigned a single security level that applies to all its contents (variables and methods). The informal security policy model includes properties such as compatibility of security level assignments with the class hierarchy. After discussing the essential features of a general object system model, and then extending the object model to incorporate mandatory label-based security, it is shown how typical database security and integrity policies can be supported by this model, with special attention to inference problems and integrity constraints. The representation of integrity constraints and classification constraints are illustrated
