【摘要】 构建系统框架的主要目的是减少系统不同功能模块之间的耦合,增加功能模块的复用。设计模式是在前人成功的基础上总结出来的一种创建对象的方法。其基本原则是在系统中加入抽象层,来分离和封装具体的实现细节。在结合现有模式设计技术的基础上,给出了一种实时数据处理系统框架分析和设计过程,并对其中用到的主要技术进行了深入探讨。给出了抽象工厂模式,建造者模式,适配器模式在Delph i环境中的具体实现方法。更多还原

【Abstract】 The main purpose of constructing system frame is to reduce coupling between function modules and enhance reuse of function modules.Design schema is a method of establishing objects which is based on the successful work of former people,and its basic principle is to add the abstract layer in the system,so that the layer can separate and occlude detail of the implementation.This paper introduces a process of analysis and design on system frame of real-time data processing.This article discusses the main technique of analysis and design schemas thoroughly.These are abstract factory schemas,builder schemas and adapter schemas.Methods of these schemas are implemented in Delphi developing environment.更多还原
