Design And Implementation Of The Direct Sales Channel Management System Based On Design Patterns

With the rapid development of computer information technology, more and more people are familiar with the concept of enterprise information management systems. A large number of software system revealed the weakness which is difficult to maintain and extend. The emergence of Design patterns effectively alleviate this problem, by learning and reuse the classic design patterns, we can make a good design and improve software quality more easily. From the nineties of last century, the Design patterns have became one of hotspots in the field of Software Engineering.Design pattern describe the classes used for solving the design proplems and the objects communicating with each other in the specified scenarios. In this paper, based on the interpretation of the theory of Design Patterns, and by referenceing a lot of good design patterns solutions, I make some research and analysis of the application of Design Patterns which is used to guide the system design.This paper aims to design a flexible, easily extensible, reusable Direct Sales Channel Management System, based on describing the relevant theory of Design Pattern in detail, I focus on how to apply the Desin Patterns to the system architecture design and detailed functions design. Both of the improved MVC patten and the improved Front Controller pattern could be applied for system design in other business areas. This article also introduces the application of the design pattern and their combinations, including the pair of the Template Method and Singleton, the Command, the combination of Factory Method and Strategy. The common ideas and method solving design problem discussed in this article could also be shifted to other modes. Good feedback of system operators also proves the correctness and effectiveness of system design.
