Google Data Catalog ODBC Driver

The Google Data Catalog ODBC Driver is a powerful tool that allows you to connect with live data from Google Data Catalog, directly from any applications that support ODBC connectivity.

Access Google Data Catalog data like you would a database - read, write, and update Google Data Catalog Schemas, Tables, etc. through a standard ODBC Driver interface.



Create dynamic charts and perform analytics based on Google Data Catalog data in Clear Analytics.

The CData ODBC Driver for Google Data Catalog enables access to live data from Google Data Catalog under the ODBC standard, allowing you work with Google Data Catalog data in a wide variety of BI, reporting, and ETL tools and directly, using familiar SQL queries. This article shows how to use Clear Analytics, a Microsoft Excel Add-In, to connect to Google Data Catalog as an ODBC source and create queries, tables, and charts (including PivotTables) based on Google Data Catalog data.

Connect to Google Data Catalog Data


Configure the ODBC Data Source Name

If you have not already done so, provide values for the required connection properties in the data source name (DSN). You can use the built-in Microsoft ODBC Data Source Administrator to configure the DSN. This is also the last step of the driver installation. See the "Getting Started" chapter in the help documentation for a guide to using the Microsoft ODBC Data Source Administrator to create and configure a DSN.

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.

When you configure the DSN, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

Configure the Data Source in Clear Analytics

  1. Open Excel and navigate to the CLEAR ANALYTICS ribbon. Once there, open the Data Manager.
  2. Select Database as the data source.
  3. In the Set Connection section, click the option to create a new database.
  4. Select Microsoft ODBC Data Source as the data source and click OK.
  5. Select the DSN you already configured from the drop-down menu.
  6. Back on the Set Connection section, select Standard (ANSI ODBC) Query Builder as the SQL Builder Provider and click Next.
  7. Select the Schema/Owner and choose the domains (tables) that you wish to use in Clear Analytics.
  8. Prepare your data objects as needed by customizing the display names and descriptions of the tables and columns.
  9. For the vast majority of the CData ODBC Drivers, you will not set a key date for your domains.
  10. In the Domain Relations section, add any relational information between tables.
  11. In the Domain Tree section, create groups for your data and add the available items to the groups.
  12. Review the summary of your data and click Finish.

Create a Chart with Google Data Catalog Data

You are now ready to create a chart with Google Data Catalog data.

Create a New Query

  1. Click Repository in the CLEAR ANALYTICS ribbon.
  2. Create a new query.
  3. Select the columns you wish to retrieve.
  4. Set the aggregation type for your data (use the blank entry if you do not wish to aggregate the data).
  5. Set filters and formulas by dragging columns to the lower window.
  6. Name your query and click Save.

Build a Chart Based on a Query Report

With the query created, you are now ready to execute a report and display a chart.
  1. Click Report Explorer in the CLEAR ANALYTICS ribbon.
  2. In the Report Explorer pane, click the 'New Report' icon in the toolbar.
  3. Select the query you just created.
  4. Name the report and click 'Save and Execute'.
  5. Click the Results tab within the Report Explorer
  6. Expand your report and drag the chart to the Excel spreadsheet.
  7. In the resulting PivotChart window, drag the fields (columns) to the Filters, Legends, Axis (Categories), and Values windows.

With a new data source in Clear Analytics established and a chart created, you are ready to begin analysis of Google Data Catalog data. With the ODBC Driver for Google Data Catalog and Clear Analytics, you can perform self-service analytics in Excel with live data, directly from Google Data Catalog.
