【摘要】 本文针对传统MIS系统的局限,提出了柔性化MIS系统的概念和定义.着重介绍了一个柔性化MIS系统NMS开发实例,介绍其设计思想和实现该系统柔性化所具备的支撑模块及这些模块的设计要点和功能等,还介绍了该系统的体系结构。在该系统中用户可以灵活地定义或修改数据模式,而且输入、输出、查询、修改、删除和统计等模块均为通用的,不因数据模式或系统功能的修改而变动源程序。源程序中的用户库名和所有条件成分均以参数或宏变量形式出现。最后还对柔性化MIS系统所具有的易扩充性和易移植性两大特点作了总结。更多还原

【Abstract】 The concept and the definition of the flexible MIS, which is directed against the traditional MIS, are advanced in this paper. The achieved example of flexible MIS, named NMS.is introduced emphatically,and its designing thought,its supporting modules used to achieve the flexibility of the NMS.the design gists and the functions of these modules,and the setup of the NMS are introduced in this paper too. The modules can be agilely defined and modified by the user in the system. These modules such as input .output, modification, detection,and statistics are in common use,and the programs needn’t be modified after the modules or the functions are changed. All the names of user databases and the conditional sections in the program are described with parameters or macro arguments.At last,the extensible and transportable characters of the flexible MIS are summarized in the paper.更多还原
