| Abstract: | In multilevel secure relational databases,the security level of data may change based on the change of content,context,time,etc.An approach to assign security to data is utilizes security constraints.The technique in constraint processing during query,update,and database design operations in multilevel secure relational database is discussed.Some technical difficulties and further works need to be done are put forward. |
