通用型MIS软件的系统设计

The System Design of Universal MIS Programmes

ＭＩＳ软件通用性差、生命周期短、利用率低是较为普遍的问题。开发通用性ＭＩＳ软件是解决这一问题的唯一途径。为此结合笔者ＭＩＳ开发经验，提出在数据库结构的设计方面，通过建立环境数据库使其具备自适应能力；在程序设计方面，阐述了通用型功能模块及通用型控件的系统设计，在此基础上，提出通过选配或调整参数文件的方式来开发通用型ＭＩＳ软件的新思路。

The MIS application systems have common problems of poor universal application , short lifetime and low efficiency. The only way to solve these problems is to develop the universal MIS programmes. According to the writer's experience of developing the MIS , it is proposed in this paper that in the design of the database structure , the MIS is made to be self-adaptable through the set up of the environmental database ; and in the design of the programmes , on the basis of the system design of universal function modules and universal control parts , the new thought of develping the universal MIS programmes through the way of selecting or adjusting the parameter files is also proposed.
