计算机行业网络考试系统中试题库的设计

摘要

Questions database is the core of the network test system. For the current problems of design of Questions database, the paper proposed improved algorithm of the binary algorithm to avoid questions in order to avoid duplication and to questions on the test database and the amount of paper the size and quality control > construction and application of computer industry test database. Practice shows that the questions database and related strategies to improve intelligence and a-daptive of the traditional test database and to improve the exam's validity and reliability.%试题库是网络考试系统的核心,针对目前试题库设计中的问题,提出二进制规避算法的改进算法以避免试题重复,并用以对试题库和试卷题量规模和质量进行控制,构建并应用计算机行业试题库,实践证明该试题库及相关策略改善传统试题库的智能性与自适应性,提高试题的效度和信度.
