Data Democratization with Domo

By: Jeff Burtenshaw

Overview of this book

Domo is a power-packed business intelligence (BI) platform that empowers organizations to track, analyze, and activate data in record time at cloud scale and performance. Data Democratization with Domo begins with an overview of the Domo ecosystem. You’ll learn how to get data into the cloud with Domo data connectors and Workbench; profile datasets; use Magic ETL to transform data; work with in-memory data sculpting tools (Data Views and Beast Modes); create, edit, and link card visualizations; and create card drill paths using Domo Analyzer. Next, you’ll discover options to distribute content with real-time updates using Domo Embed and digital wallboards. As you advance, you’ll understand how to use alerts and webhooks to drive automated actions. You’ll also build and deploy a custom app to the Domo Appstore and find out how to code Python apps, use Jupyter Notebooks, and insert R custom models. Furthermore, you’ll learn how to use Auto ML to automatically evaluate dozens of models for the best fit using SageMaker and produce a predictive model as well as use Python and the Domo Command Line Interface tool to extend Domo. Finally, you’ll learn how to govern and secure the entire Domo platform. By the end of this book, you’ll have gained the skills you need to become a successful Domo master.

Using Data Blend

Data Blend is a data sculpting tool that creates non-materialized views of your datasets. One way to think of a blend is a highly scalable equivalent of Excel's VLOOKUP function. Blends are useful when you want to do lookup translations on large tables in memory via a mapping table. Blends are also useful for appending (merging or performing a union) datasets into a single dataset. Blends are dataset definitions and, once saved, can be viewed in the dataset catalog. Blends can be created via the BLEND option on the Datasets page. Blends live in the Adrenaline cache, so they are in-memory fast.

Let's learn how to create a Data Blend.

Creating a Data Blend

Picking up from where we left off in the Creating a Data View section, let's use a blend to merge the Opportunity Leaders and Opportunity Laggards datasets into a single non-materialized dataset:

  1. Click on the DATA item in the Domo main menu bar.
  2. Click on Blend in the MAGIC TRANSFORM...
