采用基于角色的访问控制模型来保证系统的安全性。角色概念显示了企业中的工作职能。传统的锁定协议和时间戳排序调度器分别基于先入先得和时间戳顺序的原则来使多个冲突的事务可串行化。在本文中，我们讨论了一种基于分配给事务的角色的重要性的并发控制。我们在角色上定义了一个显著的支配关系。讨论了一种基于角色概念的角色排序调度器。我们将RO调度器与两阶段锁定(2PL)协议进行了比较。
A role-based access control model is used to make a system secure. A role concept shows a job function in an enterprise. Traditional locking protocols and timestamp ordering schedulers are based on principles "first-comer-winner" and "timestamp order" to make multiple conflicting transactions serializable, respectively. In this paper, we discuss a concurrency control based on the significancy of roles assigned to transactions. We define a significantly dominant relation on roles. We discuss a role ordering (RO) scheduler based on the role concept. We evaluate the RO scheduler compared with the two-phase locking (2PL) protocol.
