Overview

Looker is a modern data platform in Google Cloud that lets you analyze and visualize your data interactively. You can use Looker to do in-depth data analysis, integrate insights across different data sources, build actionable data-driven workflows, and create custom data applications.

What is LookML?

LookML (Looker Modeling Language) generates abstracted SQL and provides a modeling layer between the database and user. It is Looker’s proprietary language that provides an abstraction layer for SQL databases.

Specifically, LookML is a language for describing dimensions, aggregates, calculations, and data relationships in a SQL database. Looker uses a model written in LookML to construct SQL queries against a particular database. It creates the layer between that SQL database and how the business user interacts with it.

As such, it defines many different things, like how to join tables, how to define custom tables, how to define fields from the database, and the logic for new fields. In this lab, you will get hands-on experience with the fundamentals of LookML.
