Design and Realization of Employment Management System in Colleges and Universities

一,项目简介

在如今社会上,About the above information processing,No enterprise or individual will ignore,How to make the information fast transfer,File and stored query,Using the model of paper records before already do not conform to the requirements of the currently used.所以,Employment information management in colleges and universities improve,Also in order to for better maintenance of university employment information,The emergence of university employment management system becomes autopilot are indispensable.Through the development of university employment management system,Not only can put this to use,Make knowledge results in,Also to strengthen the knowledge memory,To expand the knowledge reserve,Is a good way to improve yourself.Through the development of specific,For the entire software development process of master,不论是前期的设计,Or subsequent coding test,Has a very in-depth understanding of.

The university employment management system through theMySQL数据库与Eclipse工具进行开发,University employment management system can realize the recruitment information management,简历管理,邀请面试管理,简历投递管理,用户管理,The company management, etc.

Through the university employment management system for the processing of information,Make information processing more system,更加的规范,这是一个必然的结果.Already processed good information,Whether it is used to find,还是分析,On the efficiency will be multiplied improve,Let the computer become more in line with the production needs,Become people indispensable to an information processing tool,To realize the green office,Save social resources,To make its contribution for environmental protection.
