摘　　要：为适应行业改革过程中对信息系统需求变化,针对目前政务信息系统基本结构,结合B/S和C/S的优劣,提出了以智能客户端技术为主体,采用工作流、基于角色访问控制、系统安全等技术相结合的敏捷系统框架。以四川农机政务系统的建设过程为实践背景,分析了政务系统的基本组成、系统模型、数据服务框架及业务流程定义、解释和执行机制,用角色控制理论构建直线职能型组织结构中各级角色的访问权和操作权分配控制模型及工作流中各业务活动的权限管理,探讨渗透系统全程的安全机制与实现。To satisfy the changes of requirements in information system in the industry innovation,according to the current basic architecture of government information systems,combined the advantages and disadvantages in the Browser/Server（B/S） and Client/Server（C/S）,a smart framework,mainly composed of smart-clients,is put forward,using the workflow and integrating the technologies of role access control and system security.Based on the case of the building process of the agricultural machinery management system in Sichuan,the basic structure of this system,the system models,the data service architecture and the definition,explanation and execution mechanism of the workflow is analyzed.The allocation model for authorities of different roles in linear and functional architecture,and the authorities in all kinds of activities in the workflow are built based on role access control.The security policy throughout the system and its implementation is discussed.
