摘　　要：针对数据存储量大引起的访问广域网服务器速度慢、不能对访问的客户进行细粒度的权限控制问题,研究了B/S模式下基于.NET平台的图像资源管理器的设计和实现技术。系统综合采用权限管理模型、动态加载、文档对象模型(DOM)等技术以及非点击无刷新伸缩控制方法,实现了图像资源管理器的分权限控制、高速访问以及无刷新高效联动等操作。实验验证了方法的可行性。To solve the slow rate of server within the wide area network because of the large memory capacity of date access and the impossibility to control the customer′s access in fine-grained level,a design and implementation technique of Image Resource Manager based on.NET framework is studied.The methods of using authority management model,dynamic load,DOM technology combining with database technology and so on are given to realize different authorities of users,the high speed to access and the association of the adjacent windows without refresh.The method of companding nodes of the trees without clicking and refresh is proposed.Finally,an experiment is presented to verify the feasibility of the method.
