several group number, then with b ± a, =c,c is is methyl b two vertical box between of accurate size学科的理论与方法，以人机交互方式
several group number, then with b ± a, =c,c is is methyl b two vertical box between of accurate size. Per-2~3 measurement, such as proceeds of c values are equal and equal to the design value, then the vertical installation accurate. For example a, b, and c valueswhile on horizontal vertical errors for measurement, General in iron angle code bit at measurement level points grid errors, specific method is from baseline to methyl vertical box center line distance for a,, to b vertical box distance for b, list can measured

数据模型：是对数据的某种抽象表示形式，是描述数据的一组概念和定义。数据模型决定了数据项的组织方式。是指在数据库中对现实世界数据特征的抽象、表示和处理的方式，它一般可分为概念、逻辑、物理三个层次。
实体：数据所代表的事件或事物。实体可以使具体的人、事、物，也可以是抽象的概念或联系
数据项：描述实体的一个属性。
