Information Interface Of School Affairs Based On Java

For many years, of software development has experienced many stages. However, systems resource problem solving and run time overdue cost too much and. the final products are not satisfied as well. Therefore software development personnel expect a sort of theory and technology to enough use current resource to build their own application program by the way of piling. This theory and technology are software components. Software component technologies improve the development efficiency, enhance systems reliability and maintainability. At that time, software components and Internet that are becoming the most two important increasing points are getting highly attention in software products area. The rapid development of software components make development model of basic component assemble application become a kind of new development pattern and development environment. Until now software components have become a sign of new generation software theory and technique development. Based on the possibilities of component software development, the component technology naissance is targeted, which makes different language and verified developers cooperated together to structure new softwares. Software component programming design based on is another advancement since Object-Oriented theory, this programming thought has noticed theory meaning and development foreground.This paper firstly analyses both the structure and principle of model of component. Secondly, studies the distribution and application of software component in multi-levels. Further more introduces the architecture of three-layers B\S (browser\server) pattern and discusses strategy and method of software engineering according to software component. Finally this thesis demonstrates the key technology of designing, using, and comply system development. This paper mainly guides the principle, technology and software engineering method of software component, and multi-layer stucture especially on software component application development.
