Use CData Connect AI to Access IBM Cloud Object Storage Data in Microsoft Power Pivot

This article will explain how to use CData Connect AI to present IBM Cloud Object Storage data as OData services and then consume the data in Microsoft Excel's Power Pivot business intelligence tool. Follow the steps below to retrieve IBM Cloud Object Storage data in Power Pivot.

Connect to IBM Cloud Object Storage from Power Pivot

To work with IBM Cloud Object Storage data from Power Pivot, we need to connect to IBM Cloud Object Storage from Connect AI, provide user access to the connection, and create a Workspace for the IBM Cloud Object Storage data.

Connect to IBM Cloud Object Storage from Connect AI

CData Connect AI uses a straightforward, point-and-click interface to connect to data sources.

1. Log into Connect AI, click Sources, and then click Add Connection

2. Select "IBM Cloud Object Storage" from the Add Connection panel

3. Enter the necessary authentication properties to connect to IBM Cloud Object Storage.

   Register a New Instance of Cloud Object Storage

   If you do not already have Cloud Object Storage in your IBM Cloud account, follow the procedure below to install an instance of SQL Query in your account:

   1. Log in to your IBM Cloud account.
   2. Navigate to the page, choose a name for your instance and click Create. You will be redirected to the instance of Cloud Object Storage you just created.

   Connecting using OAuth Authentication

   There are certain connection properties you need to set before you can connect. You can obtain these as follows:

   API Key

   To connect with IBM Cloud Object Storage, you need an API Key. You can obtain this as follows:

   1. Log in to your IBM Cloud account.
   2. Navigate to the Platform API Keys page.
   3. On the middle-right corner click "Create an IBM Cloud API Key" to create a new API Key.
   4. In the pop-up window, specify the API Key name and click "Create". Note the API Key as you can never access it again from the dashboard.

   Cloud Object Storage CRN

   If you have multiple accounts, specify the CloudObjectStorageCRN explicitly. To find the appropriate value, you can:

   • Query the Services view. This will list your IBM Cloud Object Storage instances along with the CRN for each.
   • Locate the CRN directly in IBM Cloud. To do so, navigate to your IBM Cloud Dashboard. In the Resource List, Under Storage, select your Cloud Object Storage resource to get its CRN.

   Connecting to Data

   You can now set the following to connect to data:

   • InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
   • ApiKey: Set this to your API key which was noted during setup.
   • CloudObjectStorageCRN (Optional): Set this to the cloud object storage CRN you want to work with. While the connector attempts to retrieve this automatically, specifying this explicitly is recommended if you have more than Cloud Object Storage account.

   When you connect, the connector completes the OAuth process.

   1. Extracts the access token and authenticates requests.
   2. Saves OAuth values in OAuthSettingsLocation to be persisted across connections.
   
4. Click Save & Test
5. Navigate to the Permissions tab in the Add IBM Cloud Object Storage Connection page and update the User-based permissions.

Add a Personal Access Token

When connecting to Connect AI through the REST API, the OData API, or the Virtual SQL Server, a Personal Access Token (PAT) is used to authenticate the connection to Connect AI. It is best practice to create a separate PAT for each service to maintain granularity of access.

1. Click on the Gear icon () at the top right of the Connect AI app to open the settings page.
2. On the Settings page, go to the Access Tokens section and click Create PAT.
3. Give the PAT a name and click Create.
4. The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.

Configure IBM Cloud Object Storage Endpoints for Power Pivot

After connecting to IBM Cloud Object Storage, create a workspace for your desired table(s).

1. Navigate to the Workspaces page and click Add to create a new Workspace (or select an existing workspace).
2. Click Add to add new assets to the Workspace.
3. Select the IBM Cloud Object Storage connection (e.g. IBMCloudObjectStorage1) and click Next.
4. Select the table(s) you wish to work with and click Confirm.
5. Make note of the OData Service URL for your workspace, e.g. https://cloud.cdata.com/api/odata/{workspace_name}

With the connection, PAT, and Workspace configured, you are ready to connect to IBM Cloud Object Storage data from Power Pivot.

Import IBM Cloud Object Storage Tables in Power Pivot

Follow the steps below to import tables that can be refreshed on demand:

1. In Excel, click Data -> Get Data -> From Other Sources -> From OData Feed
2. Fill out the OData feed URL (e.g. https://cloud.cdata.com/api/odata/{workspace_name})
3. On the next screen, select Basic and configure the username and password. Password will be your PAT.

4. Select the tables that you would like to import into Excel

5. After selecting your table(s) and clicking Load, you should see the data appear in an Excel spreadsheet

6. Now, click the Power Pivot tab on the ribbon, and then select Add to Data Model. This can now work with your IBM Cloud Object Storage data in Power Pivot.
