<> Project introduction
For the design of CET-4 and CET-6 online examination system , System development mainly adopts java Language Technology , It is applied in the design of the whole system MySQL Database to complete data storage , It is developed according to the current situation of CET-4 and CET-6 online examination system , The network management of CET-4 and CET-6 online examination system is realized according to the actual needs , All kinds of information are stored orderly , After entering the page of CET-4 and CET-6 online examination system , Before starting to operate the main control interface , The main functions include administrator ： home page , Personal Center , user management , Examination score management , Announcement management , Examinee notification management , Test question management , Test paper management , Examination management , user ： home page , Personal Center , Examination score management , Announcement management , Examinee notification management , Examination management and other functions .
This paper mainly describes the development background of CET-4 and CET-6 online examination system , The system mainly introduces the requirements analysis and functional requirements , And the system is tested and summarized in detail . Specifically from the business process , Database design and system structure . We hope to use advanced computer technology and network technology to change the current situation of CET-4 and CET-6 online examination system , Improve management efficiency .
