Use CData Connect Cloud to connect to Google Data Catalog from AppSheet and build custom business apps using live Google Data Catalog 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 Cloud, you get instant, cloud-to-cloud access to Google Data Catalog data for business applications. This article shows how to create a virtual database for Google Data Catalog in Connect Cloud and build a simple app from Google Data Catalog data in AppSheet.

CData Connect Cloud provides a pure MySQL, cloud-to-cloud interface for Google Data Catalog, allowing you to build reports from live Google Data Catalog 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 Google Data Catalog, leveraging server-side processing to quickly return the requested Google Data Catalog data.

Create a Virtual MySQL Database for Google Data Catalog Data

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

  1. Log into Connect Cloud and click Databases.
  2. Select "Google Data Catalog" from Available Data Sources.
  3. Enter the necessary authentication properties to connect to Google Data Catalog.

    Google Data Catalog uses the OAuth authentication standard. Authorize access to Google APIs on behalf on individual users or on behalf of users in a domain.

    Before connecting, specify the following to identify the organization and project you would like to connect to:

    • OrganizationId: The ID associated with the Google Cloud Platform organization resource you would like to connect to. Find this by navigating to the cloud console.

      Click the project selection drop-down, and select your organization from the list. Then, click More -> Settings. The organization ID is displayed on this page.

    • ProjectId: The ID associated with the Google Cloud Platform project resource you would like to connect to.

      Find this by navigating to the cloud console dashboard and selecting your project from the Select from drop-down. The project ID will be present in the Project info card.

    When you connect, the OAuth endpoint opens in your default browser. Log in and grant permissions to the application to completes the OAuth process. For more information, refer to the OAuth section in the Help documentation.

  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 Google Data Catalog data from AppSheet.
