数据模型由一个个数据表组成，这些数据表中包含多个字段列。
本节将为您介绍如何查看或修改列的属性，如修改列名、查看绑定字段、设置是否为空、是否为一、隐藏字段等。
1. 选择列
选择一个数据表的列，右侧将出现该列的属性。
2. 查看或修改属性
按照您的需求修改属性设置项即可。
属性 | 说明 |
|---|---|
名称 | 该字段在数据模型中的名称，可以修改。 |
是否可空 | 设置该列是否允许有空值。 |
是否唯一 | 设置该列是否唯一。请确保与字段的实际情况相符。 |
绑定 | 查看对应数据库中的对象。 |
逻辑数据类型 | 字段的数据类型。 |
数据类别 | 指定字段的数据类别。 数字类型的字段可指定为货币或地理经纬度。 文本类型的字段可指定为地理位置或图片数据。用于图片解析和地图读取数据。 |
