The Design And Implementation Of The Test Paper Creator System Based On Dynamic Probablity

With rapid development of computer technology in the world, computer technology has been widely used in the teaching. The test paper creator system is the most important area of computer teaching revolution of colleges. Using database technology to storage course information, and using computer information management technology to manage course subject, and using decision arithmetic to draw out the subject for teachers’ demand, can generate test paper. It can greatly solve the problem of the division of teaching and testing, and reflect the fairness of test. It can get teachers out of formulating questions, and can raise work efficiency and avoid resource consume.The paper designs and develops the test creator system.The main job is as follows, the first is to analyze the system background and the current situation of research at home and abroad. The second is to learn the related key technology, such as system architecture, Delphi development platform, database access technology, and analyses the characteristic of the C/S structure and B/S structure and to put forward the C/S structure according to the hardware and software condition of the college. The third is to analyze the requirement analysis and design of the system, and give user requirement. The system includes five management module, basic information management module, systems management module, test questions management module, test paper creator module, course management module and knowledge management module. The fourth is to define each module’s function, and build conceptual data model, logical data model and physical data model which contain five tables-test_question table, course_theme, course_table, point_table and middle_table. The fifth is to set up the multilayer filter model and dynamic probability model to the question of Entrance Examination by means of hierarchy filter, and has realized the test paper creator system successfully. The sixth is implementing of the system. The paper uses Delphi language to develop the system based on the system requirement analysis and design. The last is testing of system.The test of the system mainly base on Black Box Testing and select the important function to test the system.The system has been realized and it is tested that the system is stable and can satisfy the demanding through application. And it has taken important action in the development of education info.
