The Designing And Implementation Of The B/S-base Online Examination System

At present along with the computer network technology and data bank technology's development, the online paperless test system because of its characteristics and so on fairness, accuracy, flexibility, timeliness as well as conveniences, has become one kind of test which and the authentication way internationally generally uses. This system realized synthesized the networking and the data bank technology, used the campus net resources, better served for the school teaching management.This system uses the B/S structure, according to the traditional test process and actual situation, this system's gross structure and the functional module have been proposed. Then the online testingsystem has constructed by the PHP technology and the MYSQL backstage database through the system structure design, the table design and front end developed. It has many functions, such as online examination, the distinction of user register, the management of score, the management of paper conveniently, the management of user's information, according to the topic production examination paper, examining the operation test papers automatically and so on. This satisfied the conventional request and the design initial period guiding principle basically.In the system realizes in the process, in the multianalysis online test system has needed the key solution several key questions: Uses the field the match to realize the student to register, the teacher and the manager user registers the function; In the examination paper production process, follows the random principle, proposed the stochastic iteration searching algorithm, causes the production the test question to satisfy under the controlled condition the stochastic selected topic, avoids the human factor; Examines test papers automatically in view of the operation topic, examines test papers the procedure using the VBA compilation, uses ADO the connection and the refresh data.Because the length limits is impossible to achieve attends to every detail, but involves to the performance history in the key point, the difficulty, as well as the solution has carried on the description. Finally, summarized system's characteristic and the superiority and the deficiency, and has made the forecast to future development and the application prospect.
