为了满足印刷品质量检测系统快速处理数据的需要,进行了数据库系统结构体系的设计。分析了印刷品检测系统的数据操作过程,设计出检测系统的E-R图。在此基础上,通过设计检验标准表、缺陷类型表、缺陷原因表、缺陷详情表、质检员表和印刷品信息表,实现检测系统面向关系数据库的表示。根据检测系统的特点与数据库表的逻辑设计,给出了数据库的物理实现。
In order to meet the needs of the rapid processing data of the printing quality inspection system, the structure of the database system is designed. By analyzing the data operation process of the printed matter detection system, the E- R diagram of the detection system is designed. Based on that, it can realize the representation of a relational database for the detection system through designing each table such as standards , defect-types, defect- reasons , defect- details , users and batch - information. Eventually , it presents the physical implementation of the database , according to the characteristics of the detection system and the logical design of database table.
