It first introduces the background of the online examination system, its significance and researching situation. Then in the entire design introduces the B/S three-tier architecture, selects JSP and Java as development language, utilizes Tomcat as a Web server, chooses SQL Server as the backend database, through the Servlet, JavaBean, JDBC to connect the client and back-end database.
