Create IBM Cloud Object Storage-Connected Business Apps in AppSheet



Use CData Connect Server to connect to IBM Cloud Object Storage from AppSheet and build custom business apps using live IBM Cloud Object Storage data.

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 IBM Cloud Object Storage data for business applications. This article shows how to create a virtual database for IBM Cloud Object Storage in Connect Server and build a simple app from IBM Cloud Object Storage data in AppSheet.

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

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

    Register a New Instance of Cloud Object Storage

    If you do not already have Cloud Object Storage in your IBM Cloud account, follow the procedure below to install an instance of SQL Query in your account:

    1. Log in to your IBM Cloud account.
    2. Navigate to the page, choose a name for your instance and click Create. You will be redirected to the instance of Cloud Object Storage you just created.

    Connecting using OAuth Authentication

    There are certain connection properties you need to set before you can connect. You can obtain these as follows:

    API Key

    To connect with IBM Cloud Object Storage, you need an API Key. You can obtain this as follows:

    1. Log in to your IBM Cloud account.
    2. Navigate to the Platform API Keys page.
    3. On the middle-right corner click "Create an IBM Cloud API Key" to create a new API Key.
    4. In the pop-up window, specify the API Key name and click "Create". Note the API Key as you can never access it again from the dashboard.

    Cloud Object Storage CRN

    If you have multiple accounts, you will need to specify the CloudObjectStorageCRN explicitly. To find the appropriate value, you can:

    • Query the Services view. This will list your IBM Cloud Object Storage instances along with the CRN for each.
    • Locate the CRN directly in IBM Cloud. To do so, navigate to your IBM Cloud Dashboard. In the Resource List, Under Storage, select your Cloud Object Storage resource to get its CRN.

    Connecting to Data

    You can now set the following to connect to data:

    • InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
    • ApiKey: Set this to your API key which was noted during setup.
    • CloudObjectStorageCRN (Optional): Set this to the cloud object storage CRN you want to work with. While the connector attempts to retrieve this automatically, specifying this explicitly is recommended if you have more than Cloud Object Storage account.

    When you connect, the connector completes the OAuth process.

    1. Extracts the access token and authenticates requests.
    2. Saves OAuth values in OAuthSettingsLocation to be persisted across connections.
  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 IBM Cloud Object Storage data from AppSheet.

Connect to IBM Cloud Object Storage in AppSheet

The steps below outline connecting to CData Connect Server from AppSheet to create a new IBM Cloud Object Storage 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, IBMCloudObjectStorage1
    • 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 IBM Cloud Object Storage, you can start building apps on IBM Cloud Object Storage 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., IBMCloudObjectStorage1).
  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.
