设计题目：在线作业管理系统的设计与实现
I
摘 要
网络技术和计算机技术发展至今，已经拥有了深厚的理论基础，并在现实中
进行了充分运用，尤其是基于计算机运行的软件更是受到各界的关注。加上现在
人们已经步入信息时代，所以对于信息的宣传和管理就很关键。因此学生作业信
息的管理计算机化，系统化是必要的。设计开发在线作业管理系统不仅会节约人
力和管理成本，还会安全保存庞大的数据量，对于学生作业信息的维护和检索也
不需要花费很多时间，非常的便利。
在线作业管理系统是在 MySQL 中建立数据表保存信息，运用 SSM 框架和
Java 语言编写。并按照软件设计开发流程进行设计实现。系统具备友好性且功能
完善。本系统实现了作业管理，作业答案管理，作业批阅管理，教学资源管理，
作业提交管理以及作业统计等功能。
在线作业管理系统在让学生作业信息规范化的同时，也能及时通过数据输入
的有效性规则检测出错误数据，让数据的录入达到准确性的目的，进而提升在线
作业管理系统提供的数据的可靠性，让系统数据的错误率降至最低。

Abstract
Network technology and computer technology have developed so far, they
already have a solid theoretical foundation and have been fully used in reality,
especially the software based on computer operation has attracted the attention of all
walks of life. In addition, now that people have entered the information age, the
promotion and management of information is very important. Therefore, it is
necessary to computerize and systemize the management of student work information.
Designing and developing an online homework management system will not only
save manpower and management costs, but also store a huge amount of data safely,
and it does not take a lot of time to maintain and retrieve student homework
information, which is very convenient.
The online job management system is to build a data table to save information in
MySQL, using SSM framework and Java language to write. And in accordance with
the software design and development process for design and implementation. The
system is friendly and fully functional. This system realizes the functions of
homework management, homework answer management, homework review
management, teaching resource management, homework submission management,
and homework statistics.
While the online homework management system standardizes student homework
information, it can also detect incorrect data in a timely manner through the validity
rules of data input, so that data entry can achieve the purpose of accuracy, thereby
improving the reliability of the data provided by the online homework management
system , To minimize the error rate of system data.
Key Words：Online job management system; MySQL; SSM framework
