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!



You can use updategrams to insert, update, and delete Google Data Catalog data. This guide shows how to use the CData BizTalk Adapter for Google Data Catalog to generate updategram schemas and instances.

In this article, you will create updategrams that can be executed by the CData BizTalk Adapter for Google Data Catalog. You will design a schema and use it as a template for generating insert, update, and delete updategrams.

Add the Adapter for Google Data Catalog to Your Project

Use the Add Adapter wizard to add the adapter to a BizTalk Server project in Visual Studio. You will use the adapter to query Google Data Catalog for metadata about the table you want to modify.

  1. Right-click on the project in the Solution Explorer and click Add -> Add Generated Items.
  2. Select Add Adapter Metadata in the resulting dialog box.
  3. In the resulting Add Adapter Wizard, select the CData BizTalk Adapter for Google Data Catalog from the list view.
  4. In the Port menu, leave the selection blank. Or, select a receive location or send port that has been configured to use the adapter.
  5. When you click Next, the Schema Wizard is displayed.

Generate a Schema for an Updategram

Follow the steps below to create a schema in a BizTalk Server project in Visual Studio.

  1. If you have not already done so, add the Google Data Catalog adapter to your project.
  2. On the Connection String page of the Add Adapter wizard, enter authentication credentials and other connection properties, if they were not already configured in the send port or receive location. 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.

    See the "BizTalk Configuration" chapter in the help documentation for more information on the required connection properties.

  3. On the Schema Information page, click Send Port in the General Options section. Select Updategram from the CommandType menu. If you are using the adapter in a solicit-response send port, disable the One-Way option.
  4. On the next page, Statement Information, select the type of the updategram: Insert, Update, or Delete. Select the Table name and the columns you want to include in the schema. If you want to update or delete, the Id column is required.

    Note: When you create the updategram, you are limited to modifying the columns you include in the schema.

  5. Click Next to view a summary of the schema and finish the wizard to create the schema. The resulting .xsd file is added to your project.

Generate Insert, Update, and Delete Instance Messages

After you create the updategram schema, you can use the .xsd file to generate the updategram: Right-click the .xsd file and select Generate Instance. You can also use this file as a template to manually create updategrams. Below are example generated updategram instances for inserts, updates, and deletes:

Insert

An example of INSERT is below. In this instance, there is only an after block, which specifies how the data will change.

<ns0:parameters xmlns:ns0="http://www.cdata.com/GoogleDataCatalogProvider"> <ns0:sync> <ns0:before></ns0:before> <ns0:after> <ns0:Schemas Type="Type_0" DatasetName="DatasetName_1" /> </ns0:after> </ns0:sync> </ns0:parameters>

Update

An example of UPDATE is below. In this instance, there is both a before block (how the data currently exists in the table) and an after block (how the data will change).

<ns0:parameters xmlns:ns0="http://www.cdata.com/GoogleDataCatalogProvider"> <ns0:sync> <ns0:before> <ns0:Schemas Id=001d000000YBRseAAH></ns0:Schemas> </ns0:before> <ns0:after> <ns0:Schemas Type="Type_0" DatasetName="DatasetName_1" ></ns0:Schemas> </ns0:after> </ns0:sync> </ns0:parameters>

Delete

An example for DELETE is below. The after block will be empty to show that it is removing the item.

<ns0:parameters xmlns:ns0="http://www.cdata.com/GoogleDataCatalogProvider"> <ns0:sync> <ns0:before> <ns0:Schemas Id=001d000000YBRseAAH></ns0:Schemas> </ns0:before> <ns0:after></ns0:after> </ns0:sync> </ns0:parameters>
