Design And Realization Of Medical Multimedia On-line Test System

Today, many school' s have converted their testing methods from paper tests to computer tests. Computer testing has advantages over traditional paper testing methods. Computer-administered tests save printing and paper costs, lighten teacher's trouble and improve efficiency. Taking advantage of computer information analysis, catering to a medical university 's needs and and the like, I developed a medical multimedia online test system.Medical Multimedia On-line the test system was developed using SQL Server 2000 database and Delphi software. Several functional modules were designed. This paper discusses some technologies of the system including DCOM, MD5, multimedia transmission, transaction processing, and normal test. The test system supports many functions, such as: automatic exam scoring, simultaneous testing students, random selection of test questions, administration of test questions, administration of users, administration of scores and so forth. Especially on the basis of the traditional textless exam, it added multimedia functions (video, audio, picture). It is very fit for medicine test.The paper includes two parts: the first part illustrated some problems that must be consider for design a medical multimedia online test system, including architecture of the test system, a compositional part, functional modules, and system interface. The second part illustrated important technologies and difficulty resolutions, especially how to upload and download a mutimedia file of the system. It introduced FTP fashion for this way.An evaluation of the testing system showed that the program was stable, and met the university's needs for a computerized medical examination. The system is ready to be deployed for regular use.
