Study On Development Pattern Of B/S Framework Software System

With the development of the Internet technology, because the software based on B/S framework is flexible, easy to operate, to deploy and maintain cost little, it has got fast popularization and has been applied to each field of national economy extensively.But on the other hand, with the continuous improvement of the computing power and the growth of people's demand of the software function, the software product becomes huger and huger, there are more and more uncertain factors in the software development course, construction cycle and the risk of development are difficult to control. All of these are restricting the development of large-scale software.This reflects very obviously in the software system of B/S framework. Compare with C/S framework, B/S framework software is still a new thing. Its development idea, development course etc. are not ripe enough. Therefore it has aggravated the degree of difficulty of development of B/S software.With the continuous progress of the development approach of software, a large number of software development patterns emerged under the two major systems: .NET and J2EE. They each does things in its own way, vied each other, permeated each other in the same time, what made people dazzled.To ameliorate the state effectively, and give a better play to the advantage of B/S framework software, through the development practice of school management system, this article studied the Rational Unified Process, MVC design patterns, etc., absorbed the outstanding development idea among the present software development course, analyzed and perfected the development patterns of B/S framework software. Through circular development and system layers, this article has solved the questions in B/S framework software development such as risk controlling, development efficiency; demand analyzing and systematic elasticity, robustness, security, etc.We have got the good result while applied the thought of this kind of development patterns. Controlled development course reduces the systematic development risk; ripe development patterns improves software development efficiency; the good software framework guarantees systematic elasticity and stability; authentication based on form, authorization based on role and communication basedon SSL, ensured the security of system performance.Thereby, by adopting this kind of development patterns of B/S framework software, it can reduce the enterprise's risk during the course of software development effectively, accelerate the renewal speed of the software product, and help enterprises to put out more outstanding software product. And then, it can raise our software production level, and promote our software development patterns to renew continuously, progress continuously.
