Abstract	Concepts of roles are significant to design and implement access control models in secure information systems. A role shows a job Junction in an enterprise. In addition to keeping systems secure, objects have to be consistent in presence of multiple transactions. Traditional locking protocols and timestamp ordering schedulers are based on principles "first-comer-winner" and "timestamp order" to make multiple transactions serializable, respectively. Each transaction is associated with a role. We define significancy of role where shows how significant each role is in an enterprise. We discuss a novel type of scheduler for concurrency control so that multiple conflicting transactions are serializable in a significant order of roles of transactions.
