Integrate Live AlloyDB 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 AlloyDB 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 AlloyDB data.

CData Connect AI provides a pure SQL, cloud-to-cloud interface for AlloyDB, allowing you to easily integrate with live AlloyDB 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 AlloyDB, leveraging server-side processing to quickly return AlloyDB data.

Configure AlloyDB Connectivity for Power Apps

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

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

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

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

   The following connection properties are usually required in order to connect to AlloyDB.

   • Server: The host name or IP of the server hosting the AlloyDB database.
   • User: The user which will be used to authenticate with the AlloyDB server.
   • Password: The password which will be used to authenticate with the AlloyDB server.

   You can also optionally set the following:

   • Database: The database to connect to when connecting to the AlloyDB Server. If this is not set, the user's default database will be used.
   • Port: The port of the server hosting the AlloyDB database. This property is set to 5432 by default.

   Authenticating with Standard Authentication

   Standard authentication (using the user/password combination supplied earlier) is the default form of authentication.

   No further action is required to leverage Standard Authentication to connect.

   Authenticating with pg_hba.conf Auth Schemes

   There are additional methods of authentication available which must be enabled in the pg_hba.conf file on the AlloyDB server.

   Find instructions about authentication setup on the AlloyDB Server here.

   Authenticating with MD5 Authentication

   This authentication method must be enabled by setting the auth-method in the pg_hba.conf file to md5.

   Authenticating with SASL Authentication

   This authentication method must be enabled by setting the auth-method in the pg_hba.conf file to scram-sha-256.

   Authenticating with Kerberos

   The authentication with Kerberos is initiated by AlloyDB Server when the ∏ is trying to connect to it. You should set up Kerberos on the AlloyDB Server to activate this authentication method. Once you have Kerberos authentication set up on the AlloyDB Server, see the Kerberos section of the help documentation for details on how to authenticate with Kerberos. 👁 Configuring a connection (Salesforce is shown)
   

4. Click Save & Test
5. Navigate to the Permissions tab in the Add AlloyDB 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 AlloyDB data from Power Apps.

Connecting to CData Connect AI

To use Connect AI to integrate AlloyDB data into your Power Apps, you need a new SQL Server connection:

1. Log in to Power Apps
2. Click Dataverse -> Connections -> New connection
3. Select SQL Server 👁 Creating a new SQL Server Connection
   
4. In the connection wizard:
   
   
   • Choose to connect directly
   • Set SQL server name to tds.cdata.com,14333
   • Set SQL database name to the name of the AlloyDB connection (e.g. AlloyDB1)
   • Set Username to a Connect AI user (e.g. [email protected])
   • Set Password to the PAT for the above user
   • Click Create 👁 Connecting to Connect AI
     

Building a Data-Centric App for AlloyDB Data

With the connection to Connect AI configured, you are ready to integrate live AlloyDB data into the apps you build in Power Apps.

1. Log in to Power Apps
2. Click Create and select "SQL" 👁 Creating a new app from data
   
3. Select the SQL Server connection you created
4. Search for or choose a table to work with
5. Click Connect 👁 Connecting to AlloyDB data
   
6. Customize the newly created app just like you would any other, including changing the layout and setting the fields exposed in BrowseScreen, DetailScreen, and EditScreen 👁 Customizing the AlloyDB data app
   

At this point, you have an app with read and write access to live AlloyDB data that you can save and publish for use within your organization.
