Create SAS Data Sets-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 Server, you get instant access to SAS Data Sets data for business applications. This article shows how to create a virtual database for SAS Data Sets in Connect Server and build a simple app from SAS Data Sets data in AppSheet.

CData Connect Server provides a pure SQL Server interface for SAS Data Sets, allowing you to easily build reports from live SAS Data Sets data in AppSheet — without replicating the data to a natively supported database. As you build visualizations, AppSheet generates SQL queries to gather data. Using optimized data processing out of the box, CData Connect Server pushes all supported SQL operations (filters, JOINs, etc) directly to SAS Data Sets, leveraging server-side processing to quickly return the requested SAS Data Sets data.

Create a Virtual SQL Server Database for SAS Data Sets Data

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

1. Login to Connect Server and click Connections.
2. Select "SAS Data Sets" from Available Data Sources.
3. Enter the necessary authentication properties to connect to SAS Data Sets.

   Set the following connection properties to connect to your SAS DataSet files:

   Connecting to Local Files

   • Set the Connection Type to "Local." Local files support SELECT, INSERT, and DELETE commands.
   • Set the URI to a folder containing SAS files, e.g. C:\PATH\TO\FOLDER\.

   Connecting to Cloud-Hosted SAS DataSet Files

   While the driver is capable of pulling data from SAS DataSet files hosted on a variety of cloud data stores, INSERT, UPDATE, and DELETE are not supported outside of local files in this driver.

   Set the Connection Type to the service hosting your SAS DataSet files. A unique prefix at the beginning of the URI connection property is used to identify the cloud data store and the remainder of the path is a relative path to the desired folder (one table per file) or single file (a single table). For more information, refer to the Getting Started section of the Help documentation.

4. Click Save Changes
5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions.

With the virtual database created, you are ready to connect to SAS Data Sets data from AppSheet.

Connect to SAS Data Sets in AppSheet

The steps below outline connecting to CData Connect Server from AppSheet to create a new SAS Data Sets data source.

1. Log into AppSheet.
2. Click the letter icon in the top-right corner, then select Account Settings.
3. Click the Sources tab and click + New Data Source. Then, select Cloud Database.
4. Set the connection information to the following:
   • Type: SQLServer
   • Server: the endpoint for your instance, including port, for example, CONNECT_SERVER_URL,3306
   • Database: the virtual database, for example, SASDataSets1
   • Username: a Connect Server user with permissions for the database
   • Password: the password for the above Connect Server user
   • SSL: Require SSL
5. Click Test. Then, click Authorize Access.

Create an App

Once you create the data source for SAS Data Sets, you can start building apps on SAS Data Sets data.

1. Start by clicking + Create -> App -> Start with existing data.
2. Name the app and select an appropriate category, based on your data. Then, click Choose your data.
3. Select the newly created data source (e.g., SASDataSets1).
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.
