基于SSM勤工助学管理系统设计与实现

摘  要

随着我国教育需求不断增加，高校教育资源有限，教育经费相对不足的情况下，利用现代信息技术发展高等教育，不仅充分利用了优秀的教育资源，而且为更多的人提供接受高等教育的机会，同时这也是极大促进了高校的信息化发展。

其中勤工助学管理系统就是信息化教育体系中不可或缺的管理工具。勤工助学管理系统是高等学校教学工作的核心，是改进学生的关键因素。随着勤工助学规模的日益扩大，学生人数不断增多，教学资源日趋紧张，对勤工助学工作的要求和难度也大大增加。传统的勤工助学管理模式已无法应对日趋复杂的管理工作，建立高效、科学、规范的勤工助学网络管理信息系统成为教学管理发展的必然趋势。从勤工助学工作的实际出发，解决工作中关键性的难点问题，并充分利用计算机技术，实现勤工助学管理工作全过程的计算机管理，帮助管理人员从复杂烦琐工作中解放出来，通过完善管理信息化的制度，可以规范管理，保证勤工助学管理效果，提高管理效率，有效地提高校勤工助学管理工作的规范化和现代化水平，使得勤工助学管理工作走向无纸化办公和规范化、现代化的轨道上

本勤工助学管理系统采用的数据库是Mysql，使用java技术开发。在设计过程中，充分保证了系统代码的良好可读性、实用性、易扩展性、通用性、便于前后期维护、操作方便以及页面简洁等特点。

关键词：勤工助学管理系统，Mysql、java、ssm

ABSTRACT

With the increasing demand for education in China, the limited educational resources and the relatively insufficient educational funds in Colleges and universities, the use of modern information technology to develop higher education not only makes full use of excellent educational resources, but also provides more people with opportunities to receive higher education. At the same time, it also greatly promotes the development of information technology in Colleges and universities.

The work study management system is an indispensable management tool in the information education system. Work study management system is the core of teaching work in Colleges and universities, and is the key factor to improve students. With the expansion of the scale of work study program, the number of students is increasing, and the teaching resources are becoming increasingly tense. The requirements and difficulties of work study program are also increasing. The traditional work study management mode has been unable to cope with the increasingly complex management work. The establishment of efficient, scientific and standardized work study network management information system has become an inevitable trend of the development of teaching management. Starting from the reality of work study work, this paper solves the key and difficult problems in the work, and makes full use of computer technology to realize the computer management of the whole process of work study management, so as to help the management personnel liberate from the complicated and tedious work. By improving the management information system, it can standardize the management, ensure the management effect of work study work, improve the management efficiency, and has the practical significance We should effectively improve the standardization and modernization level of the work study management, and make the work study management move towards paperless office, standardization and modernization

This work study management system uses MySQL database, using Java technology development. In the design process, it fully ensures the good readability, practicability, expansibility, universality, easy maintenance, easy operation and concise page of the system code.

Key words: work study management system, mysql, Java, SSM
