一种基于角色的知识管理系统的动态组装模

在分析了知识管理系统(KMS)的组装技术和基于角色访问控制(RBAC)的特点的基础上,提出了一种基于角色的知识管理系统动态组装模型,并且还进一步给出了该模型中访问控制表的设计、知识管理系统的动态组装模型和客户程序与知识管理系统构成组件间的交互过程。基于角色的访问控制可以将KMS的使用置于多级的访问控制保护之下,增加了KMS与知识库的安全系数,从而有效地支持知识的动态重用、知识使用过程的动态重组,增强知识管理系统的分布式处理能力和规模可扩展能力,还可以在不影响KMS运行的前提下,实时的更新、升级系统的各个功能;易于实现有效的知识管理,以及知识资源的共享和充分运用。最后,通过一个实例说明了给出模型的实现技术。

Dynamic assembled model for the knowledge management system based on role

Based on the analysis of assembly technologies of KMS (Knowledge Management Systems) and characters of RBAC (role-based Access Control) technology, a role-based dynamic assembed model is proposed. In this model, the design of access control tables, dynamic assembled model of KMS and interaction process between client program and components of KMS are also introduced. RBAC makes use of KMS under the mutilevel access control and improves the safe modulus so it can effectively support dynamic reuse of knowledge and recombination of knowledge use process, strengthen distrbuted processing capability and scalability of KMS, and update or upgrade each function in real time. Thus, it is casy to realize and make full use of the effective knowledge management and knowledge resources sharing. Finally, a case is introduced to illustrate the realization technologies of the proposed mode
