Integrate Live Greenplum Data into Custom Business Apps Built in Power Apps

Power Apps is a service for building and using custom business apps that connect to your data and work across the web and mobile — without the time and expense of custom software development. When paired with CData Connect AI, you get instant, cloud-to-cloud access to Greenplum data from the apps you build using Power Apps. This article shows how to connect to Connect AI from Power Apps and build an app based on live Greenplum data.

CData Connect AI provides a pure SQL, cloud-to-cloud interface for Greenplum, allowing you to easily integrate with live Greenplum data in Power Apps — without replicating the data. CData Connect AI looks exactly like a SQL Server database to Power Apps and uses optimized data processing out of the box to push all supported SQL operations (filters, JOINs, etc) directly to Greenplum, leveraging server-side processing to quickly return Greenplum data.

Configure Greenplum Connectivity for Power Apps

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

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

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

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

   To connect to Greenplum, set the Server, Port (the default port is 5432), and Database connection properties and set the User and Password you wish to use to authenticate to the server. If the Database property is not specified, the default database for the authenticate user is used.

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 Greenplum data from Power Apps.
