Connect to AtomData

Please follow the steps below to connect to the AtomData data source.

1. Click "New Data Connection" in the upper right corner of the Data Connection page.

2. Select the AtomData data source from the Data Source types.

3. Fill in the parameters for the data source as required.

• Name: The name of the connection, must be unique.
• Machine Address: The address of the database. If the URL field is filled, the URL will be prioritized.
• Port: The port of the database. If the URL field is filled, the URL will be prioritized.
• Username: The username for the database.
• Password: The password for the database.
• Database: The name of the database. If the URL field is filled, the URL will be prioritized.
• Encoding: The encoding setting for the database connection.
• Prioritize using database comment for dataset title: Whether to display the table name or the table comment. When enabled, the title is displayed; when disabled, the table comment is displayed.
• Data Gateway: Fill in the Data Gateway ID when the connection is made through a data gateway.
• URL: The JDBC URL for the database.
• Transaction Isolation Level for Read Behavior: The transaction isolation level for read behavior. This setting only affects data reading; data writing still uses the default isolation level.
• Hierarchical Loading of Schemas and Tables: When turned off, both schemas and tables are loaded simultaneously. When turned on, schemas and tables are loaded hierarchically. The connection process only loads schemas, quickly integrating the data source into the system.
• Show Tables Only Under Specified Database/Schema: When this option is selected and the database field is not empty, only tables under this database are displayed.

4. After filling in the parameters, click the "Verify" button to obtain the verification result (verifying the connectivity between HENGSHI SENSE and the configured data connection; adding is not allowed if the verification is not passed).

5. Click to execute the preset code, and the preset code corresponding to the data source will pop up. Click the execute button.

6. Click the "Add" button to add the configured AtomData connection.

Please note

Note:

1. Parameters marked with * are required, while others are optional.
2. When connecting to a data source, the preset code must be executed. Failure to do so will result in certain functions being unavailable during data analysis. Additionally, when upgrading from versions prior to 4.4 to 4.4, the preset code needs to be executed for existing data connections in the system.
