Create Data Visualizations Based On IBM Cloud Object Storage Data in Mode
Mode is a collaborative data platform that combines SQL, R, Python, and visual analytics in one place. When paired with CData Connect AI, you get instant, cloud-to-cloud access to IBM Cloud Object Storage data for use in data visualizations. This article shows how to connect to IBM Cloud Object Storage in Connect AI, connect to IBM Cloud Object Storage data in Mode, and create a simple visualization using that data.
CData Connect AI provides a pure cloud-to-cloud interface for IBM Cloud Object Storage, allowing you to build data visualizations from live IBM Cloud Object Storage data in Mode — without replicating the data to a natively supported database. In order to create visualizations, users write SQL queries to gather data. Using optimized data processing out of the box, CData Connect AI pushes all supported SQL operations (filters, JOINs, etc.) directly to IBM Cloud Object Storage, leveraging server-side processing to quickly return the requested IBM Cloud Object Storage data.
Configure IBM Cloud Object Storage Connectivity for Mode
Connectivity to IBM Cloud Object Storage from Mode is made possible through CData Connect AI. To work with IBM Cloud Object Storage data from Mode, we start by creating and configuring a IBM Cloud Object Storage connection.
- Log into Connect AI, click Sources, and then click Add Connection
- Select "IBM Cloud Object Storage" from the Add Connection panel
-
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:
- Log in to your IBM Cloud account.
- 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:
- Log in to your IBM Cloud account.
- Navigate to the Platform API Keys page.
- On the middle-right corner click "Create an IBM Cloud API Key" to create a new API Key.
- 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.
- Extracts the access token and authenticates requests.
- Saves OAuth values in OAuthSettingsLocation to be persisted across connections.
- Click Save & Test
-
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.
- Click on the Gear icon () at the top right of the Connect AI app to open the settings page.
- On the Settings page, go to the Access Tokens section and click Create PAT.
-
Give the PAT a name and click Create.
- The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.
With the connection configured and a PAT generated, you are ready to connect to IBM Cloud Object Storage data from Mode.
Connect to IBM Cloud Object Storage in Mode
The steps below outline connecting to CData Connect AI from Mode to create a new IBM Cloud Object Storage data source.
- Log-in to Mode
- In the top-left corner of the screen, click the down-arrow next to your name and select Connect a Database...
- On the next screen, select Microsoft SQL Server.
- Enter the Microsoft SQL Server credentials:
- Display Name: the name for the connection.
- Host/Port: enter tds.cdata.com in the Host field and 14333 in the Port field.
- Database name: enter the Connection Name of the CData Connect AI data source you want to connect to (for example, IBMCloudObjectStorage1).
- Username: enter your CData Connect AI username. This is displayed in the top-right corner of the CData Connect AI interface. For example, [email protected]
- Password: enter the PAT you generated on the Settings page
- At the bottom of the page, click Connect to ensure that you can connect to CData Connect AI.
- Upon success, the following screen appears.
Your connection is now available for use in Mode. To connect to additional data sources from your CData Connect AI account, repeat the setup steps above, changing the value for Database for each data source.
Creating A Mode Visualization
To create a visualization in Mode, follow these steps:
- On the current screen, click New Report. The SQL query text editor appears.
Enter the following query:
SELECT * FROM [IBMCloudObjectStorage].[Objects];
Click Run. The app now shows the query result:
- Running the query activates the New Chart tab. Click this tab and select Pie Chart.
- Now, drop a dimension in the Color section and a measure in the Angle section.
We have now created a visualization of IBM Cloud Object Storage data in Mode using CData Connect AI!
