Create Greenplum-Connected Business Apps in AppSheet

Use the CData Cloud Hub to connect to Greenplum from AppSheet and build custom business apps using live Greenplum data.

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

The CData Cloud Hub provides a pure MySQL, cloud-to-cloud interface for Greenplum, allowing you to build reports from live Greenplum 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, the CData Cloud Hub pushes all supported SQL operations (filters, JOINs, etc.) directly to Greenplum, leveraging server-side processing to quickly return the requested Greenplum data.

Create a Virtual MySQL Database for Greenplum Data

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

  1. Log into Cloud Hub and click Databases.
  2. Select "Greenplum" from Available Data Sources.
  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.

  4. Click Test Database.
  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 Greenplum data from AppSheet.

Connect to Greenplum in AppSheet

The steps below outline connecting to the CData Cloud Hub from AppSheet to create a new Greenplum 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: MySQL
    • Server: the endpoint for your instance, including port, for example, myinstance.cdatacloud.net:3306
    • Database: the virtual database, for example, Greenplum1
    • Username: a Cloud Hub user with permissions for the database
    • Password: the password for the Cloud Hub user
    • SSL: Require SSL
  5. Click "Test Connection"
  6. Click "Authorize Access"

Create an App

Once you create the data source for Greenplum, you can start building apps on Greenplum 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 (e.g., database-1)
  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.
