            Test paper auto-production system based on database
 Abstract£º This paper analyses the actual demand of auto-production for test paper system in the course of concrete teaching activity at first. Then taking teaching of English of high school as the background ,it designs and realizes a Test paper auto-production system. First, it Explains the design for the database structure, then introduces the detailed one to the realization of each main module among them . It can automatically find and organize a certain number of test questions in various types with different degrees of difficulty in certain scope in the database to form a reasonable test paper. The method is that the Characteristic properties of test questions are recorded firstly, and then according to user¡¯s demands in type ,difficulty ,knowledge scope, etc ,by changing related data of the course to logical ones a suitable and satisfied to restrain test paper of universal property on the basis of series of data files is linearly programmed¡£
