Design And Implementation Of Online Examination System Based On Ajax Technology

With the continuous development of Web technology,online examination system has been widely applied in various fields and performance and functionality of the system are put forward higher requirements.therefore,the ability to provide more efficient,more convenient,more comprehensive online examination system will be a major problem in the future that design the online examination system.In this background,the design and development based on Ajax technology online examination system.System builts on the MySQL+Apache+PHP and use Ajax technology to optimize and improve the functionality of the system.This thesis analyzes the technology works and its advantages and clarify the characteristic of asynchronous interaction of Ajax technology. Ajax technology allows Web applications to asynchronous interact and greatly enhance the user experience and Web operational efficiency. System with user login management function,test management function, faculty department management function,user management function,online test management function,paper management function,automatic grading and management function and so on,and meet the needs of users to the system.First of all,this thesis describs the background of the development of online examination system and analyze the needs of the schools to system.Then it discusses the system logic model and data model building process and describes the system implementation process of each module in detail in the implementation section.Finally it shows the system test results and conclusions and proposes an idea to improve the system in the future.
