Visualize Live GitHub Data in the Power BI Service

Power BI transforms your company's data into rich visuals for you to collect and organize so you can focus on what matters to you. When paired with CData Connect AI, you get instant access to GitHub data for visualizations, dashboards, and more. This article shows how to build and publish a dataset from GitHub data in Power BI and then create reports on GitHub data in the Power BI service.

CData Connect AI provides a pure SQL interface for GitHub, allowing you to easily build reports from live GitHub data in Power BI — with no need to replicate the data. As you build visualizations, Power BI generates 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 GitHub, leveraging server-side processing to quickly return GitHub data.

NOTE: You can also import GitHub data into Power BI through Connect AI (instead of using the on-premise gateway). Read how in the related Knowledge Base article.

Configure GitHub Connectivity for Power BI

Connectivity to GitHub from Power BI is made possible through CData Connect AI. To work with GitHub data from Power BI, we start by creating and configuring a GitHub connection.

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

2. Select "GitHub" from the Add Connection panel
👁 Selecting a data source

3. Enter the necessary authentication properties to connect to GitHub.

   GitHub uses the OAuth 2 authentication standard. To authenticate using OAuth, create an app to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL connection properties. See the Getting Started chapter of the CData help documentation for an authentication guide.

4. Click Save & Test
5. Navigate to the Permissions tab in the Add GitHub Connection page and update the User-based permissions. 👁 Updating 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. 👁 Creating a new PAT
   
4. 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 GitHub data from Power BI.

Connecting to Connect AI from Power BI

To connect to and visualize live GitHub data in the Power BI service, install the on-premise data gateway, add a data source to the gateway from the Power BI service, and publish a dataset from Power BI Desktop to the service.

Install the On-Premises Data Gateway

The Microsoft on-premise data gateway provides secure data transfer between connected data sources and various cloud-based Microsoft tools and platforms. You can read more about the gateway in the Microsoft documentation.

You can download and install the gateway from the Power BI service:

1. Log in to PowerBI.com.
2. Click the Download menu and click Data Gateway. 👁 Download the Data Gateway
   
3. Follow the instructions for installation, making note of the name of the gateway.

Add GitHub as a Data Source to the Power BI Service

Once you have installed the data gateway, you add Connect AI as a data source to the Power BI service:

1. Log in to PowerBI.com.
2. Click the Settings menu and click "Manage gateways." 👁 Settings -> Manage gateways
   
3. Click "ADD DATA SOURCE" and configure the connection to Connect AI:
   
   
   • Set Data Source Name to something like ConnectCloudGitHub.
   • Choose SQL Server as the Data Source Type.
   • Set Server to tds.cdata.com,14333.
   • Set Database to the name of your GitHub connection (e.g. GitHub1).
   • Set Authentication Method to Basic.
   • Set Username to a Connect AI user (e.g. [email protected])
   • Set Password to the PAT for the user above.

Publish a Dataset from Power BI Desktop

With the gateway installed and Connect AI added as a datasource to the Power BI service, you can publish a dataset from Power BI Desktop to the service.

1. Open Power BI, click Get Data -> More, then select SQL Server database, and click Connect.
👁 Create a new connection in Power BI

2. Set the connection properties and click OK.
   • Set Server to tds.cdata.com,14333.
   • Set Database to the name of your GitHub connection (e.g. GitHub1).
   • Set Data Connectivity mode to DirectQuery*.
   👁 Connect to CData Connect AI instance
   * DirectQuery enables live query processing and real-time visualizations of GitHub data.
3. In the authentication wizard, select Database, set the User name and Password properties, and click Connect.
👁 Authenticate the connection

4. Select the table(s) to visualize in the Navigator dialog.
5. In the Query Editor, you can customize your dataset by filtering, sorting, and summarizing GitHub columns. Click Edit to open the query editor. Right-click a raw to filter the rows. Right-click a column header to perform options like the following:
   • Change column data types
   • Remove a column
   • Group by columns

   Power BI detects each column's data type from the GitHub metadata reported by Connect AI.

   Power BI records your modifications to the query in the Applied Steps section, adjusting the underlying data retrieval query that is executed to the remote GitHub data. When you click Close and Apply, Power BI executes the data Retrieval query.

   Otherwise, click Load to pull the data into Power BI.

6. Define any relationships between the selected entities on the Relationships tab.
7. Click Publish (from the Home menu) and select a Workspace.

Build Reports and Dashboards on GitHub Data in the Power BI Service

Now that you have published a dataset to the Power BI service, you can create new reports and dashboards based on the published data:

1. Log in to PowerBI.com.
2. Click Workspaces and select a workspace.
3. Click Create and select Report.
4. Select the published dataset for the report. 👁 Select a dataset
   
5. Choose fields and visualizations to add to your report. 👁 Visualizing GitHub data in the Power BI service
   

Live Access to GitHub Data from Cloud Applications

Now you have a direct connection to live GitHub data from the Power BI service. You can create more data sources and new visualizations, build reports, and more — all without replicating GitHub data.
