| 摘 要： | 本文针对信息系统中出现的权限管理问题，结合信息系统开发的实践经验，对多权限信息系统中的授权机制问题进行了深入浅出的研究。针对传统授权机制的缺陷，提出了动态授权机制和增强的授权机制，最后遵循软件复用的思想，利用软件构件技术开发了权限管理构件，并在实际的信息系统开发中成功地应用了该技术。

| Abstract: | In this paper,some problems about privilege management in information system are addressed.Based on the experiences acquired in the process of information system development,the authorization mechanism of multi privilege information system is studied exhaustively.To overcome the limitations of traditional authorization mechanism,dynamic authorization mechanism and enhanced authorization mechanism are proposed.Follow the software reuse idea,based on the software component technology,privilege management component is developed and successfully used in a real information system. |
