设计了一种适合于通用在线考试的试题数据库,根据规范数据库设计的要求,设计了试题库的关系数据模型,并给出了规范化论证。在经典测试理论的基础上,提出了一种约束试卷生成的参数模型,并根据该模型设计了一种自动试卷生成的递归算法。

An on-line examination item bank is designed which can be used to the general on-line examination. According to the demands of the canonical item bank design, a relational database model is designed and its standardization demonstration is given. Based on the classic examination theory, a constraint-based parameter model of generating examination paper is proposed and a recursive arithmetic based on the model is designed.
