Introduction: In today’s world, data is the lifeblood of any organization, and businesses have to grapple with ever-increasing amounts of data. A powerful tool that can help businesses make sense of this data is Looker Studio. Looker is a business intelligence and data analytics platform that provides a comprehensive approach to data modeling, reporting, and visualization. One of the essential features of Looker Studio is the ability to blend data from multiple sources. In this blog post, we will dive into the concept of data blending in Looker and how it can help organizations get a more complete view of their data.

What is Data Blending?

Data blending is the process of combining data from multiple sources into a single view or dataset. It’s a common practice in business intelligence and data analytics that enables organizations to gain insights from disparate data sources. Data blending allows businesses to analyze and visualize data from different sources, such as databases, spreadsheets, and cloud-based services, as if they were in a single table. This process is crucial when businesses want to combine data that is stored in different formats or databases. For instance, combining customer data from a CRM system with sales data from an ERP system.

Why Use Data Blending in Looker Studio?

There are several reasons why businesses might use data blending in Looker Studio. First, data blending enables businesses to combine data from multiple sources into a single view, making it easier to analyze and gain insights. Second, data blending can help businesses to identify correlations and relationships between data sources that might not be apparent otherwise. Third, data blending can help businesses to fill in the gaps in their data by combining data from different sources. Fourth, data blending can help businesses to create more accurate forecasts and predictions by using a more comprehensive dataset.

How to Blend Data in Looker Studio?

To blend data in Looker Studio, you need to follow a few steps. First, you need to create a connection to each data source you want to blend. Looker supports various types of data sources, including SQL databases, cloud-based services, and spreadsheets. Once you have established a connection to each data source, you can create a view for each source in Looker Studio. A view is a logical representation of a dataset that defines the fields and relationships between them.

Next, you need to create a LookML join to combine the views into a single dataset. LookML is Looker’s modeling language that allows you to define relationships between views and create custom dimensions and measures. You can use LookML to specify how the data sources should be joined and what fields should be included in the blended dataset.

Finally, you can use Looker’s data visualization tools to analyze and visualize the blended dataset. Looker provides a wide range of visualization options, including charts, graphs, and dashboards, to help you gain insights from your data.

Tips for Successful Data Blending in Looker Studio Here are a few tips to keep in mind when blending data in Looker Studio:

Understand your data

Before you begin blending data, make sure you have a clear understanding of the data sources you are working with. You need to know the structure of the data, what fields are available, and what relationships exist between them.

Keep it simple

It’s easy to get carried away with data blending and create complex joins and relationships. However, it’s essential to keep it simple and only blend the data you need to achieve your goals.

Test and validate

Always test your blended dataset to ensure it is accurate and complete. Looker provides various tools to help you test and validate your data, such as the explore feature and the LookML validator.

Document your work

Documenting your data blending process is crucial to ensure that your team can understand and replicate your work. Looker allows you to add comments and descriptions to your views, joins, and dimensions, making it easier to understand your data model.

Consider performance

Blending large datasets from multiple sources can impact performance. It’s important to optimize your data model to ensure it is efficient and doesn’t cause delays when users are querying the data. Looker provides tools such as caching, database indexing, and SQL optimization to help you improve performance.

Use data security best practices

When blending data from multiple sources, it’s essential to ensure that your data is secure. Looker provides a range of security features, such as row-level security and user permissions, to help you control access to your data.
