Google Data Catalog BizTalk Adapter

Powerful BizTalk Adapters that allow you to easily connect BizTalk Server with live Google Data Catalog data through standard orchestrations.

Use the Google Data Catalog Adapters to synchronize with Google Data Catalog Schemas, Tables, etc. Perfect for data synchronization, local back-ups, workflow automation, and more!



The CData BizTalk Adapter makes it easy to process Google Data Catalog data in BizTalk by returning the data as XML. You can use this data in a BizTalk orchestration by creating an XML schema file for the table you want to access in BizTalk.

This article will show how to generate a schema to process Google Data Catalog data retrieved using the CData BizTalk Adapter. You will generate a schema for a SELECT command.

This guide shows how to use the CData BizTalk Adapter for Google Data Catalog to execute SQL commands to Google Data Catalog.

Add the Adapter for Google Data Catalog to Your Project

Follow the steps below to add the adapter to a BizTalk Server project.

  1. If you have not already done so, create a new BizTalk Server project in Visual Studio.
  2. Right-click on the project in the Solution Explorer and click Add -> Add Generated Items.
  3. Select Add Adapter Metadata in the resulting dialog box.
  4. In the resulting Add Adapter wizard, select the adapter from the list.
  5. In the Port menu, leave the selection blank. You can also select a receive location or send port that has the adapter configured as its transport type.

Generate a Schema for an SQL Command

After you select the adapter in the Add Adapter wizard, the Schema wizard is displayed. Follow the steps below to configure connection properties and retrieve the metadata for the results of the command.

  1. In the Connection String page, enter authentication credentials and other connection properties, if you did not select an adapter that you have already configured in your BizTalk application. Below is a typical connection string: ProjectId=YourProjectId;InitiateOAuth=GETANDREFRESH

    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.

  2. In the General Options section on the next page, Schema Information, select Send Port or Receive Location, depending on the adapter configuration.
  3. If you want to generate the schema for the entire result set, select the Single Message option in the Message Mode menu. If you want to generate one schema for each row in the result set, select the Message Per Row option and confirm that the root element of the message is 'row'.
  4. In the Command Type menu, select SQL Command.
  5. In the SQL Command Text box on the Statement Information page, enter an SQL command. (If you have configured a receive location or send port, the SQL command you configured is entered in the box.) This example uses the query below:

    SELECT Type, DatasetName FROM Schemas WHERE ProjectId = 'bigquery-public-data'

  6. Confirm the settings in the summary displayed by the wizard and click Finish to generate the schema.xsd file.
