Abstract


The access control database system is an important research content of the database security , role-based access control (Role-Based Access Control) is a theoretical and applied research access control model . This paper RBAC96 model family conducted a detailed analysis , and on this basis , given an extended RBAC model ( Extension RBAC) . ERBAC introduction of mandatory access control features and audit functions , mandatory access control features in the role of the authorization process , session management , and object auditing increase in the role-based access control mechanism . In software engineering , object-oriented analysis and design is more popular . Of ERBAC system using the Unified Modeling Language (Unified Modeling Language) object-oriented analysis and modeling , you can narrow the gap between the theoretical model and application system development . Therefore , this article also completed using UML static modeling and dynamic modeling process ERBAC . Finally, the combination of the actual project the Heilongjiang provincial flood control decision support system \Combined with background the Oracle8i powerful security management mechanism in DBSMS system , mainly through the introduction of the role of the rule base and mandatory access control features , to solve the shortcomings of the Oracle8i system, the lack of role constraint mechanism and improve the security level of the system , to better achieve the ERBAC model to achieve the standard of security access control policy . Research database security access control has universal significance , but also a general database security solutions for the government , enterprises and institutions in the information construction , create MIS / DSS and other information systems , with a wide range of research significance and application value .
