Abstract :
The conceptual and logical design of multilevel secure (MLS) database applications are treated in an integrated way. For the conceptual design, a powerful semantic data model is suggested in order to represent the data and security semantics of the application domain. For the logical design, a two-phase approach is developed. Phase one consists of the transformation of the database conceptualization into multilevel relational concepts, while phase two is concerned with integrity management. Enforcing the integrity in MLS databases is known to be a difficult task. Careful data modelling is a necessary prerequisite in order to arrive at consistent and secure MLS applications
