Create Cosmos DB-Connected Business Apps in AppSheet

AppSheet provides a no-code development platform for application software, which allows users to create mobile, tablet, and web applications. When paired with CData Connect Cloud, you get instant, cloud-to-cloud access to Cosmos DB data for business applications. This article shows how to connect to Cosmos DB in Connect Cloud and build a simple app from Cosmos DB data in AppSheet.

CData Connect Cloud provides a pure cloud-to-cloud interface for Cosmos DB, allowing you to build reports from live Cosmos DB data in AppSheet — without replicating the data to a natively supported database. As you create applications to work with data, AppSheet generates SQL queries to gather data. Using optimized data processing out of the box, CData Connect Cloud pushes all supported SQL operations (filters, JOINs, etc.) directly to Cosmos DB, leveraging server-side processing to quickly return the requested Cosmos DB data.

Connect to Cosmos DB in Connect Cloud

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

1. Log into Connect Cloud, click Connections and click Add Connection
2. Select "Cosmos DB" from the Add Connection panel
3. Enter the necessary authentication properties to connect to Cosmos DB.

   To obtain the connection string needed to connect to a Cosmos DB account using the SQL API, log in to the Azure Portal, select Azure Cosmos DB, and select your account. In the Settings section, click Connection String and set the following values:

   • AccountEndpoint: The Cosmos DB account URL from the Keys blade of the Cosmos DB account
   • AccountKey: In the Azure portal, navigate to the Cosmos DB service and select your Azure Cosmos DB account. From the resource menu, go to the Keys page. Find the PRIMARY KEY value and set AccountKey to this value.
4. Click Create & Test
5. Navigate to the Permissions tab in the Add Cosmos DB Connection page and update the User-based permissions.

Add a Personal Access Token

If you are connecting from a service, application, platform, or framework that does not support OAuth authentication, you can create a Personal Access Token (PAT) to use for authentication. Best practices would dictate that you create a separate PAT for each service, to maintain granularity of access.

1. Click on your username at the top right of the Connect Cloud app and click User Profile.
2. On the User Profile page, scroll down to the Personal Access Tokens section and click Create PAT.
3. Give your 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.

With the connection configured, you are ready to connect to Cosmos DB data from AppSheet.

Connect to Cosmos DB in AppSheet

The steps below outline connecting to CData Connect Cloud from AppSheet to create a new Cosmos DB data source.

1. Log into AppSheet
2. Click "My account" in the menu
3. Click the Sources tab and add a new data source
4. Select Cloud Database and set the connection information
   • Type: Sql Server
   • Server: tds.cdata.com,14333
   • Database: the Cosmos DB connection, for example, CosmosDB1
   • Username: a Connect Cloud user, for example, user@mydomain.com
   • Password: the PAT for the above Connect Cloud user
   • SSL: Require SSL
5. Click "Test Connection"
6. Click "Authorize Access"

Create an App

Once you create the data source for Cosmos DB, you can start building apps on Cosmos DB data. Start by clicking "My apps" in the menu.

1. Click to create a new app and select "Start with your own data"
2. Name the app and select an appropriate category, based on your data
3. Select the newly created data source
4. Select the table or view with the data you want

At this point, you can configure the design of your app, selecting which columns from the selected table to display, use as labels, and more. Preview the app in the preview panel and then publish or share it when ready.
