提出通过层次、结点顺序号、结点编码等字段来存储检定仪表信息的树形存储方法,按仪表属性从上至下构建仪表分类层次,每一层分类只含有一个属性值,通过父结点编号建立树形存储结构.解决了系统中区分记录格式、校验费用、考核分值、检定员、常规类型等不同仪表分类存储的问题,能清楚地显示各层之间的关系,减小数据的冗余度,提高数据操作的效率,并针对热工计量检定管理系统的数据检索给出数据操作算法.实际应用结果表明该方法操作简单,方便.
This paper presents a tree storage method for storing verification instrument information through fields such as hierarchy, node sequence number and node code. The instrument classification hierarchy is constructed from top to bottom according to the instrument attributes. Each classification contains only one attribute value, Point number to establish the tree storage structure.It solves the problems of the system of different record format, check fee, check score, checker, regular type and other different instruments classification storage, can clearly display the relationship between layers, reduce Data redundancy and improve the efficiency of data operation, and data retrieval algorithm for data retrieval of thermal measurement verification management system is given.The practical application shows that the method is simple and convenient.
