   | Show only tables under specified database/schema | If selected and the database field is not empty, only tables under that DB are shown. |

4. After filling in the parameters, click the `Validate` button to get the validation result (this checks the connectivity between HENGSHI SENSE and the configured data connection; you cannot add the connection if validation fails).

5. After validation passes, click `Execute Preset Code` to pop up the preset code for this data source, then click the execute button.

6. Click the `Add` button to add the `MongoDB` connection.

> \[!CAUTION] Please Note
>
> 1. Parameters marked with \* are required; others are optional.
> 2. When connecting to a data source, you must execute the preset code. Failure to do so may result in certain functions being unavailable during data analysis. In addition, when upgrading from a version prior to 4.4 to 4.4, you need to execute the preset code for existing data connections in the system.
