データ接続¶

In Workbench, you can easily configure and reuse secure connections to predefined data sources. Not only does this allow you to interactively browse, preview, and profile your data, it also gives you access to DataRobot's integrated data preparation capabilities.

See the associated considerations for important additional information.

Connect to a data source¶

Creating a data connection lets you explore external source data and then add it to your Use Case.

To create a data connection:

1. In the Add data modal, click Connect.

   

2. Select the data source (Snowflake in this example).

   

   Now, you can configure the data connection.

Configure the connection¶

When configuring your data connection, the required parameters are based on the selected data source as well as the authentication method. This example shows how to configure Snowflake with OAuth using new credentials.

To configure the data connection:

1. On the Configuration page, select a configuration method—either Parameters or JDBC URL.

2. Enter the required parameters for the selected configuration method.

   パラメーターJDBC URL

   

   

3. Click New Credentials and select an authentication method—either Basic or OAuth.

   保存済みの資格情報

   If you previously saved credentials for the selected data source, click Saved credentials and select the appropriate credentials from the dropdown.

   

4. 右上隅の保存をクリックします。

   

   If you selected OAuth as your authentication method, you will be prompted to sign in before you can select a dataset. See the DataRobot Classic documentation for more information about supported authentication methods and required parameters.

データセットを選択¶

Once you've set up a data connection, you can add datasets by browsing the database schemas and tables you have access to.

To select a dataset:

1. Select the schema associated with the table you want to add.

   

2. Select the box to the left of the appropriate table.

   

   With a dataset selected, you can:

   	説明
   	Click Wrangle to prepare the dataset before adding it to your Use Case.
   	Click Preview to open a snapshot preview to help determine if the dataset is relevant to your Use Case and/or if it needs to be wrangled.
   	Click Add to Use Case to add it to your Use Case, making it available to you and other team members on the Datasets tab.

   大きいデータベース

   If you want to decrease the size of the dataset before adding it to your Use Case, click Wrangle. When you publish a recipe, you can configure automatic downsampling to control the number of rows when Snowflake materializes the output dataset.

次のステップ¶

ここでは以下の操作を行うことができます。

• Perform data wrangling before adding the dataset to your Use Case.
• Add more data.
• View Exploratory Data Insights for the dataset.
• Use the dataset to set up an experiment and start modeling.
