User-role based security (URBS) is a technique for characterizing database security that takes the responsibilities of individuals into consideration when determining the security requirements of an application. In previous work, the authors developed a set of techniques for defining and analyzing URBS for an application. They extend this work by considering an actual individual's authorized access rights in an application, and by focusing on specifying, analyzing, and validating these rights. Inconsistencies and conflicts not identified when the roles were defined and analyzed, might become apparent when different roles are combined to represent the privileges for an individual. This study serves as a fundamental step toward supporting an authorization mechanism for URBS, thereby achieving management and control over all authorized accesses to an object-oriented database
