Abstract
The fast-paced development of the modern economy and the continuous
improvement and upgrading of information technology have allowed the management
of traditional data information to be upgraded to software storage, induction, and
centralized management of data information management methods. This online
examination system was born under such a large environment. It can help managers to
process huge data information in a short time. Using this software tool can help
managers improve transaction processing efficiency and achieve twice the result with
half the effort. This online test system utilizes the mature and complete SSM
framework, uses the cross-platform Java language that can develop large commercial
websites, and the Mysql database, one of the most popular RDBMS application
software, for program development. It enables users to select test questions online,
complete their answers, and view the assessment scores online. The administrator
manages question bank information, test paper information, and view student scores
and other functions. The development of the online examination system is based on
the operator's needs. The interface is simple and beautiful. The layout of the
functional modules is consistent with that of the same type of website. The program
also provides some practical solutions to the security problems of data and
information when it implements the basic required functions . It can be said that this
program helps managers to efficiently handle work affairs, and also realizes the
integration, standardization and automation of data information.
