基于扩展观察者模式的建筑劳务实名制一卡通系统的设计与实现

The Design & Realization of AS/RS Scheduling System Based on Observer Pattern

通过建筑劳务实名制一卡通系统的框架结构设计,提出完善该系统的必须解决的问题,引入观察者模式,并将这一扩展的模式应用于一卡通系统,使系统精巧、简洁,易于复用、易于扩展,有效提高了一卡通系统的开发效率和整体的性能。

This paper points out the existing problems and shortcomings of most AS/RS scheduling system and describes the framework of scheduling system.In order to solve these problems and avoid these shortcomings,the Observer pattern is introduced in this paper.The Observer pattern is applied to scheduling system by detailed analysis,which made the system compact,concise,easy to reuse and expand,and which effectively improved the developing efficiency and the whole function of the scheduling system.
