设计模式在物资管理系统中的研究与应用

he inherent complexity of software development, and low reusability of software products, severely restricts the production of software products. Design pattern method using in software development process, to a certain extent, improves the reusability of software products, and reduces software product development cycle time. This paper introduces the development of material management system of a bank using design patterns. Abstract factory pattern, state pattern, strategy pattern and observer pattern are applied to the database access module, material application module, material statistics module, and reports module. This design method optimizes the system architecture and improves system reusability.
