# 数据目录

> ClickHouse Cloud 的数据目录集成

ClickHouse Cloud 可直接连接到开放表格式数据目录，让您无需复制数据即可访问数据湖中的表。
通过此集成，数据目录中的表会作为可查询的数据库显示在 ClickHouse 中。
可通过 SQL 命令 ([DataLakeCatalog](/zh/reference/engines/database-engines/datalake)) 或 ClickHouse Cloud UI 的“数据源”选项卡进行设置。

使用 UI：

* 通过使用与 Data Catalog 对象一致字段的表单，简化设置流程
* 为已启用的数据目录集成提供统一界面
* 保存时测试连接和凭证
