Joining Multiple Data Sources in Google Data Studio: A Comprehensive Guide
Written on
Chapter 1: Introduction to Data Blending
Hello, data enthusiasts! I'm back with another insightful article about Google Data Studio. Previously, I've discussed its comparisons and shared some of my reservations about the platform. However, it’s essential to recognize that Google Data Studio is a robust tool that allows you to integrate over 400 data sources into a single report. The addition of blended sources has made it even more powerful.
To understand data blending, think of it as a JOIN operation in SQL. You have two datasets, each containing unique information, but they share at least one common data point, known as a key. If your datasets lack a key, they cannot be blended together.
For instance, consider blending your website behavior report from Google Analytics with your app usage report. This integration provides all records from the website report alongside any corresponding records from the app usage data. If a user has accessed both the website and the app, their data will be included; however, if they only used the app without visiting the site, they won’t appear in the blended data.
Section 1.1: Steps for Joining Data Sources
To effectively join multiple data sources in Google Data Studio, follow these steps:
Begin by placing your primary data source first.
Next, let’s set up a blended field.
Add a chart to your report.
Click on "Blend Data."
A panel will appear.
Choose your first data source on the left, which serves as the primary source. Then, add your second data source. Data Studio allows you to incorporate up to five data sources in a chart, but we'll focus on two for now.
Select your join key. If the field is present in both sources, it will turn green. If not, an alert will indicate this.
Remember, the key functions as a filter for the second data source. Selecting multiple keys can further restrict the records retrieved from the second dataset.
After selecting your join key, the remaining steps will be quite familiar.
Choose the dimensions and metrics you wish to display for your first data source, then repeat for the second.
You can also refine the results by applying filters or a date range. Filters and date segments added to the primary data source will carry over to the other data sources.
Once you've customized your report, click "Save." Congratulations! You've just created your first blended data chart!
If you find it simpler to create two distinct charts and later merge them, Data Studio provides a convenient shortcut. Simply select both charts, right-click, and choose "Blend Data."
