A PostgreSQL Interface for Google Analytics Data

Use the Remoting features of the Google Analytics JDBC Driver to create a PostgreSQL entry-point for data access.

There are a vast number of PostgreSQL clients available on the Internet. From standard Drivers to BI and Analytics tools, PostgreSQL is a popular interface for data access. Using our JDBC Drivers, you can now create PostgreSQL entry-points that you can connect to from any standard client.

To access Google Analytics data as a PostgreSQL database, use the CData JDBC Driver for Google Analytics and a JDBC foreign data wrapper (FDW). In this article, we compile the FDW, install it, and query Google Analytics data from PostgreSQL Server.

Connect to Google Analytics Data as a JDBC Data Source

To connect to Google Analytics as a JDBC data source, you will need the following:

  • Driver JAR path: The JAR is located in the lib subfolder of the installation directory.
  • Driver class: cdata.jdbc.googleanalytics.GoogleAnalyticsDriver

  • JDBC URL: The URL must start with "jdbc:googleanalytics:" and can include any of the connection properties in name-value pairs separated with semicolons.

    Google uses the OAuth authentication standard. To access Google APIs on behalf on individual users, you can use the embedded credentials or you can register your own OAuth app.

    OAuth also enables you to use a service account to connect on behalf of users in a Google Apps domain. To authenticate with a service account, you will need to register an application to obtain the OAuth JWT values.

    In addition to the OAuth values, set Profile to the profile you want to connect to. This can be set to either the Id or website URL for the Profile. If not specified, the first Profile returned will be used.

    Built-in Connection String Designer

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

    java -jar cdata.jdbc.googleanalytics.jar

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

    A typical JDBC URL is below:

    jdbc:googleanalytics:Profile=MyProfile;InitiateOAuth=GETANDREFRESH

Build the JDBC Foreign Data Wrapper

The Foreign Data Wrapper can be installed as an extension to PostgreSQL, without recompiling PostgreSQL. The jdbc2_fdw extension is used as an example.

  1. Add a symlink from the shared object for your version of the JRE to /usr/lib/libjvm.so. For example: ln -s /usr/lib/jvm/java-6-openjdk/jre/lib/amd64/server/libjvm.so /usr/lib/libjvm.so
  2. Start the build: make install USE_PGXS=1

Query Google Analytics Data as a PostgreSQL Database

After you have installed the extension, follow the steps below to start executing queries to Google Analytics data:

  1. Log into your database.
  2. Load the extension for the database: CREATE EXTENSION jdbc2_fdw;
  3. Create a server object for Google Analytics: CREATE SERVER GoogleAnalytics FOREIGN DATA WRAPPER jdbc2_fdw OPTIONS ( drivername 'cdata.jdbc.googleanalytics.GoogleAnalyticsDriver', url 'jdbc:googleanalytics:Profile=MyProfile;InitiateOAuth=GETANDREFRESH', querytimeout '15', jarfile '/home/MyUser/CData/CData\ JDBC\ Driver\ for\ Salesforce MyDriverEdition/lib/cdata.jdbc.googleanalytics.jar');
  4. Create a user mapping for the username and password of a user known to the MySQL daemon. CREATE USER MAPPING for postgres SERVER GoogleAnalytics OPTIONS ( username 'admin', password 'test');
  5. Create a foreign table in your local database: postgres=# CREATE FOREIGN TABLE traffic ( traffic_id text, traffic_Browser text, traffic_Sessions numeric) SERVER GoogleAnalytics OPTIONS ( table_name 'traffic');
You can now execute SELECT commands to Google Analytics: postgres=# SELECT * FROM traffic;
