Create DB2-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 DB2 data for business applications. This article shows how to create a virtual database for DB2 in Connect Server and build a simple app from DB2 data in AppSheet.

CData Connect Server provides a pure SQL Server interface for DB2, allowing you to easily build reports from live DB2 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 DB2, leveraging server-side processing to quickly return the requested DB2 data.

Create a Virtual SQL Server Database for DB2 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 "DB2" from Available Data Sources.
3. Enter the necessary authentication properties to connect to DB2.

   Set the following properties to connect to DB2:

   • Server: Set this to the name of the server running DB2.
   • Port: Set this to the port the DB2 server is listening on.
   • Database: Set this to the name of the DB2 database.
   • User: Set this to the username of a user allowed to access the database.
   • Password: Set this to the password of a user allowed to access the database.

   You will also need to install the corresponding DB2 driver:

   • Windows: Install the IBM Data Server Provider for .NET.

     On Windows, installing the IBM Data Server Provider is sufficient, as the installation registers it in the machine.config.

   • Java: Install the IBM Data Server Driver for JDBC.

     In the Java version, place the IBM Data Server Driver JAR in the www\WEB-INF\lib\ folder for this application.

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 DB2 data from AppSheet.

Connect to DB2 in AppSheet

The steps below outline connecting to CData Connect Server from AppSheet to create a new DB2 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, DB21
   • 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 DB2, you can start building apps on DB2 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., DB21).
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.
