In the daily teaching process, strengthening exercises is to teach this curriculum door key. Usual practice and final exams, such as the urgent need for many exercises to strengthen the training of students so that students exercises to do in strengthening the knowledge system, a clear reality to operate some of the knowledge points. At present, the majority of our country for teaching software testing is expensive, but also for secondary development, such as questions, the main purpose of teaching system is to design a comprehensive and practical online examination system to enable students to practice in a simulated environment, and strengthen their knowledge and to improve study score and the effect of teaching.In this paper, the use of java technology design and system design by the introduction of related technologies used for online examination system needs analysis and put forward the desired objectives. This system, through the outline design, database design, etc. to determine the overall design.

Backgrounds management implementation of the administrators delete modify student information, subject to add modify and delete topic increase modify, view grade information deleted, the administrator to add delete and modify the information function.System design is completed; constantly improve the information at the same time, a test run. Organize the students as part of the new system for the practical application of the test. System conversion, the new system a formal substitute for the original system, day-to-day running records submitted, in accordance with the specifications of the system must make the necessary changes; the difficulty should not modify or amend the record of the problem, regularly demand the formation of new proposals. For the next cycle ready to do systematic planning.
