无纸化考试数据库设计方案改进研究

在充分研究已有数据库设计方案的基础上,提出自己的完整优化设计方案:把数据库和数据表进行优化整合,对字段也提出自己的改进设计方案,并给出采用该数据库对样卷和学生答卷的处理方法。经实践证明,采用优化后的设计方案,不仅优化了数据存储结构,提高了数据库的访问速度,从一定程度上使算法的编写更加容易,从而大大提高了整个系统的效率和性能。

Improvement and Research of Database Design Scheme of No - paper Examination

Based on the research of former database design,this paper gives an integrity and optimized design:combining and optimizing the database and tables,improving the design solution of field,offering the process method of the paper.Proved by practice,the optimized design,not only optimized the data storage structure,but also increased the speed of database access.To a certain extent,the method is easy to program,thus greatly improving the efficiency and performance of the whole system.
