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 information management of
CET-4, high error rate, poor information security, high labor intensity, and
time-consuming and labor-consuming problems, the use of the web-based CET-4
online test system can effectively manage the information and make information
management more scientific and standardized.
The web-based English Level 4 online examination system uses Java language
for coding, and uses Mysql to create data tables to save the data generated by the
system. The system can provide information display and corresponding services. Its
administrator manages the test papers and the information of the question bank that
composes the test papers, checks the scores of the student test papers, and manages
classes and students. Students choose the test questions to answer the questions, and
they can view the answer scores.
In short, the web-based English Level 4 online examination system centrally
manages information and 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.
