title: 自定义对象
---
对象是存储特定于组织的数据(记录、属性和值)的结构。 Twenty 提供标准对象和自定义对象。
标准对象是为所有用户提供特定属性的内置对象。 Twenty 的标准对象示例包括“公司”和“人员”。 标准对象具有对所有 Twenty 用户可用的标准字段,如 Company.displayName。
自定义对象是您可以创建的对象,用于存储专属于您组织的信息。 它们不是内置的;您可以创建和自定义自定义对象来保存标准对象不适合存储的信息。
## 高级模式

</div>
<br />
## 工作原理
自定义对象来自确定对象形状、名称和类型的元数据表。 所有这些信息都存在于元数据模式数据库中,由表组成:
* **DataSource**:说明数据所在的详细信息。
* **Object**:描述对象并链接到数据源。
* **Field**:列出对象的字段并连接到对象。
要添加自定义对象,工作空间成员将查询 /metadata API。 这将相应地更新元数据,并根据元数据计算 GraphQL 架构,将其存储在 GQL 缓存中以备后用。

<br />
要获取数据,流程涉及通过 /graphql 端点进行查询并通过查询解析器传递。
