摘要
随着信息互联网购物的飞速发展，一般企业都去创建属于自己的管理系统。本文介绍了面向工程教育专业认证的毕业生跟踪调查反馈系统的开发全过程。通过分析企业对于面向工程教育专业认证的毕业生跟踪调查反馈系统的需求，创建了一个计算机管理面向工程教育专业认证的毕业生跟踪调查反馈系统的方案。文章介绍了面向工程教育专业认证的毕业生跟踪调查反馈系统的系统分析部分，包括可行性分析等，系统设计部分主要介绍了系统功能设计和数据库设计。
本面向工程教育专业认证的毕业生跟踪调查反馈系统有管理员，学生，企业单位。
管理员功能有个人中心，学生管理，班级信息管理，企业单位管理，教师信息管理，课程指标管理，试卷管理，试题管理，考试管理。学生可以查看教师信息，课程指标，参加考试。因而具有一定的实用性。
本站是一个B/S模式系统，采用SSM框架作为开发技术，MYSQL数据库设计开发，充分保证系统的稳定性。系统具有界面清晰、操作简单，功能齐全的特点，使得面向工程教育专业认证的毕业生跟踪调查反馈系统管理工作系统化、规范化。

Abstract
With the rapid development of information internet shopping, general enterprises are to create their own management system. This paper introduces the whole process of the development of the feedback system for engineering education professional certification. By analyzing the needs of enterprises for the graduate tracking survey feedback system for engineering education professional certification, a scheme of computer management for the graduate tracking survey feedback system for engineering education professional certification is established. This paper introduces the system analysis part of the graduate tracking survey feedback system for engineering education professional certification, including feasibility analysis, etc. the system design part mainly introduces the system function design and database design.
The engineering education professional certification for graduates tracking survey feedback system has administrators, students, business units.
Administrator functions include personal center, student management, class information management, enterprise management, teacher information management, course index management, test paper management, test management, and examination management. Students can view teacher information, curriculum indicators and take exams. So it has certain practicability.
The station is a B / S mode system, using SSM framework as the development technology, MySQL database design and development, fully ensure the stability of the system. The system has the characteristics of clear interface, simple operation and complete functions, which makes the management of tracking survey feedback system for engineering education graduates systematized and standardized.
