Research And Implementation Of Computer Application Foundation Paperless Network Examination System

With the rapid development of the technology of computer network and database, paperless network examination system becomes more and more being widely used due to its efficiency, objectivity, impartiality and accuracy. The traditional testing methods can only reflecting theory level of students, and it is low efficiency; Paperless network examination system is a test of testing computer operational level as well as reflecting theory level of students. At the same time greatly reduce the workload of teachers, to ensure a fair and reasonable test, and improve teaching efficiency.This paper analyses present situation of paperless network examination system, and on that basis, in connection with the course of Basis of Computer Applications in the vocational academies, Analysis and design a C/S structure LAN examination system, moreover, it is a more practical paperless network examination system of Basis of Computer Applications. The aspects of the research are as follows:1. The encryption technology and decryption technology is employed to process important information in the database through Backpack public key algorithm in paperless network examination system, thus the database and information safety problem is solved.2. Theory and realizing method of the technology of the automotive configuration of testing environment by system is also discussed, the principle of visiting control model to examinee folder which is based on NTFS file system is used to solve the technical problem of the automotive configuration of testing environment by system.3. Detailed analysis of the design of question and the generation of questionnaire is also analyzed, and make the questions distributed properly in broadness and difficulty, which will fulfill the testing goal of reflecting the students'theory knowledge and operation ability.4. The essay illustrates the designing principle and method of the Paperless network examination system, System process and function structure are builted scientifically and practically, the genetic algorithm is emploied to solve the problem of paper generation, that is a good idea.5. To automatically mark the students'Office papers by VBA programming technology.The system is used widely in the course of Basis of Computer Applications in the vocational academies. The effect is good, the processing function parameters correctly, easy and feasible, the goal is realized.
