role set meaning in Chinese

角色定向

Refinement to the rbac96 model , which has resulted in an improvement to ex - design of yx - ccmis , which includes : ( 1 ) introduction of two types of " mutually exclusive relationship " in role set : static and dynamic , which can be used in role assignment operation and role control . ( 2 ) introduction of context constraints , which remedies the incapability of reflecting the restricted characteristics of roles in some conditions for the rbac96 model
研究与分析了rbac96模型，从实际应用的角度对其进行了完善，包括采用了在角色集上定义两种互斥运算(静态与动态)的方式，使rbac96模型中的职责分离得到了直接的体现：引入了语境( context )约束，反映了角色在一定条件下所受的限制。
