Object-oriented Framework For Multiplexing Applications

Object Oriented Framework (00 Framework) is a large-scale software reuse technique. It has the advantages both of design reuse and code reuse, providing a powerful tool for software development based on software reuse. A majority of design and code would come from framework when it is applied to software development. Thus greatly increase efficiency of software development. Moreover , Software development based on 00 framework would greatly increase software quality because application framework is always mature and has little defects. As 00 technique grows more mature, Reuse of framework has became the most effective way in software production. Research of 00 framework will greatly promote the application of new software development methods.In this dissertation,we researched mainly the development technology of 00 framework from two sides both theoretics and practice.First ,it talked about the common concepts and pivotal technology on software reuse from technical aspect. Secondly, it discussed the common concepts and classification of the 00 framework,and compared the framework technology with other relavant techniques of software reuses. Through deeply researching on 00 framework technique and design patterns, aiming at the problem that long period of development, bad capacity for prediction and high requirement of skills of traditional down-top framework development methods. A top-down 00 framework development method based on design patterns is brought up through the analysis of traditional 00 framework development method. Consequent it construed applications architecture of J2EE and introduced the popular web framework named struts which based on J2EE. It narrated the designment and implementation of an exam system over network based on Struts, and described the composing and structure of the whole system. it expatiated on what the proposal is, how to implement, what tools be used during the development and interrelated skills.
