MIS通用查询技术的设计与实现

分析了在MIS中研制通用查询技术的必要性和重要性,根据MIS的开发实践,介绍面向对象的通用查询程序,提供了实用的查询条件设置逻辑,大大提高了程序对业务需求变化的适用性。在MIS中对于要查询的数据,相关操作仅与其类型有关。因此,可以将它们独立出来,设计成通用的组件进行封装,通过面向对象的设计方法的继承机制,将它们集成到MIS中,以备各模块重用。本文结合军械维修器材管理与辅助决策系统的开发,介绍了它的设计方法和实现技术。

The Design and Implementation of the General Technique of MIS

This paper discusses the necessity and importance of the design and implementation of the general query technique in Management Information System. According to the practice of MIS development.it introduces the object-oriented general query program.and provides applied query condition setting logic. It greatly improves the program ' s adaptability to the change of operation requirement. The operations on queried data only relate to data type in MIS,so it can be separated and designed for general encapsulation group-ware through the inherit mechanism of the object-oriented design method. It can be gathered in MIS and can be reused in each unit. This paper, based on the management of armament maintenance appliances and development of supplemental decision-making system, introduces the design methods and implementation technigues.
