| 摘 要： | 针对企业行为的特征，把权限规划到组织机构的相应部门之后，以部门来限制管理角色对权限的操作范围，简化了PRA97模型的实现难度．同时采用了基于事务的中间层技术对此模型进行相应的扩展．通过事务建立角色和权限之间的映射关系，提高了授权管理的可操作性．应用表明，这极大地减少了授权过程中的失误．

| Abstract: | Aiming at characteristics of enterprise practice, permission was given to the corresponding organization units; and the operating areas for the management roles permission were restricted in terms of organization units. The process for realizing PRA97 model was simplified. This model was extended by middle level technology based on transaction. The operational ability of authentication management was improved by establishing mapping relations between role and permission through transaction. It was shown that the misjudgement in the authenticating process was reduced in this way. |
