Abstract
Multilevel secure database systems are the systems, which each data item is assigned a security level or sensitivity level. The security classifications are assigned from complete relation to the individual data elements. To assign sensitivity levels, the capability of security constraints or classification rules is utilized. Security constraints assign the security levels on the basis of content, context, and time of data items. In this paper, we propose an integrated architecture for distributed query operations and coding of multi-levels for the purpose of providing extra security when it is stored on various sites.
