Google Data Catalog JDBC Driver

Rapidly create and deploy powerful Java applications that integrate with Google Data Catalog.



How to set Google Data Catalog data as a JDBC data source in FineReport.

The CData JDBC Driver for Google Data Catalog fully implements the JDBC standard and can provide Google Data Catalog data connectivity to a wide variety of BI, reporting, and ETL tools and custom applications. In this article, we explain how to set Google Data Catalog data as JDBC data source in FineReport and view Google Data Catalog data as a table in the Report Designer.

Set Up a JDBC Data Source of Google Data Catalog Data

Follow the instruction below to set Google Data Catalog data as a FineReport database connection.

  1. Copy the cdata.jdbc.googledatacatalog.jar file from the lib folder in the CData JDBC Driver for Google Data Catalog installation directory to the lib folder of the FineReport installation directory. You will need to copy the cdata.jdbc.googledatacatalog.lic file as well.
  2. From the Server tab, select Define Data Connection, click to add a new connection, and click JDBC.

Next we will set up the data connection definition in the window.

  1. Database: Others
  2. JDBC Driver: cdata.jdbc.googledatacatalog.GoogleDataCatalog Driver
  3. URL: A standard JDBC connection string using semicolon-separated connection properties.

    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.

    Built-in Connection String Designer

    For assistance in constructing the JDBC URL, use the connection string designer built into the Google Data Catalog JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

    java -jar cdata.jdbc.googledatacatalog.jar

    Fill in the connection properties and copy the connection string to the clipboard.

    When you configure the JDBC URL, 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.

    A typical JDBC URL is below:

    jdbc:googledatacatalog:ProjectId=YourProjectId;
  4. Click Connection pool attributes and set Test before getting connections to No.

Click Test connection to ensure you have configured the connection properly. With the connection to Google Data Catalog set up, you can use it as FineReport data source.

Select Google Data Catalog Data in the Report Designer.

  1. Click to add a new template data set and select DB query to open the database query window.
  2. Choose the JDBC connection that you created from the dropdown list.
  3. The Google Data Catalog entities will appear as tables on the left pane.
  4. Write a SELECT statement for the Google Data Catalog data tables and columns that you want to load.
  5. Click preview and data is shown as table.

With these simple steps, Google Data Catalog can be used as a JDBC data source in FineReport.
