I
摘 要
互联网发展至今,无论是其理论还是技术都已经成熟,而且它广泛参与在社
会中的方方面面。它让信息都可以通过网络传播,搭配信息管理工具可以很好地
为人们提供服务。针对四六级报名信息管理混乱,出错率高,信息安全性差,劳
动强度大,费时费力等问题,采用四六级报名与成绩查询系统可以有效管理,使
信息管理能够更加科学和规范。
四六级报名与成绩查询系统在 Eclipse 环境中,使用 Java 语言进行编码,使
用 Mysql 创建数据表保存本系统产生的数据。系统可以提供信息显示和相应服务,
其管理员管理考试和考场信息,管理学生,成绩以及老师信息。老师查询考试以
及考场信息,管理学生成绩,查看公告。学生对四六级考试进行报名,查询考场
以及考试成绩。
总之,四六级报名与成绩查询系统集中管理信息,有着保密性强,效率高,
存储空间大,成本低等诸多优点。它可以降低信息管理成本,实现信息管理计算
机化。

Abstract
Since the development of the Internet, both its theory and technology have
matured, and it has been widely involved in all aspects of society. It allows
information to be disseminated through the Internet, and it can serve people well with
information management tools. In view of the chaotic management of the registration
information of the fourth and sixth levels, high error rate, poor information security,
high labor intensity, and time-consuming and labor-intensive problems, the use of the
fourth and sixth level registration and score inquiry system can be effectively
managed, and the information management can be more scientific and standardized.
The registration and score query system for levels four and six is in the Eclipse
environment, using Java language for coding, and using Mysql to create a data table
to save the data generated by the system. The system can provide information display
and corresponding services. Its administrator manages exams and exam room
information, manages students, grades, and teacher information. Teachers inquire
about exams and exam room information, manage student scores, and view
announcements. Students register for CET-4 and CET-6 exams, check the
examination room and test results.
In short, the registration and score query system for levels 4 and 6 centrally
manages information, which has many advantages such as strong confidentiality, high
efficiency, large storage space, and low cost. It can reduce the cost of information
management and realize the computerization of information management.
