A private training session for your team. Groups can be of any size, at a location of your choice including our training centres.

Certificate of Attendance

As a Google Cloud Partner, Jellyfish has been selected to run this one-day Developing Data Models with Look ML course.

During the session, we’ll show you how to develop scalable, performant LookML (Looker Modelling Language) models that provide your business users with the standardised, ready-to-use data.

By the end of the course, you’ll be able to start building and maintaining LookML models to curate and manage data in your organisation’s Looker instance.

Our Developing Data Models with LookML course is available as a private training session that can be delivered via Virtual Classroom, at our training centre in The Shard, or at a location of your choice in the UK.

Course overview

Who should attend:

This course is suitable for data developers who are responsible for data curation and management within their organisations, as well as data analysts interested in learning how data developers use LookML to curate and manage data in their organisation’s Looker instance.

What you'll learn:

By the end of this course, you will be able to:

Define LookML basic terms and building blocks
Use the Looker Integrated Development Environment (IDE) and project version control to modify LookML projects
Create dimensions and measures to curate data attributes used by business users
Create and design Explores to make data accessible to business users
Use derived tables to instantaneously create new tables
Use caching and data groups in Looker to speed up SQL queries

Prerequisites

To get the most out of this course, you should have a basic understanding of SQL, Git, and the Looker business user experience. If you have no previous experience as a data explorer in Looker, we recommend you first complete the Analysing and Visualising Data in Looker course.
