🔹 Core Concepts You Must Know

Before diving in, let’s understand the building blocks of Looker:

1. 📁 Explores

An Explore is where you go to query and analyze your data. Think of it as a smart, visual SQL query builder. You select dimensions and measures to build your report.

2. 📐 Dimensions

Dimensions are descriptive attributes of your data — things like Customer Name, Date, Country, or Product Category. They help you slice and filter your data.

3. 📏 Measures

Measures are calculated values — like Total Revenue, Count of Orders, or Average Session Duration. They answer the “how much” or “how many” questions.

4. 📋 Looks

A Look is a saved report or visualization created from an Explore. You can save, share, and embed Looks across your organization.

5. 📊 Dashboards

A Dashboard is a collection of multiple Looks and visualizations displayed together on one screen for a comprehensive view of your data.

6. 🧱 LookML

LookML (Looker Modeling Language) is the backbone of Looker. It defines how your database tables relate to each other and how metrics are calculated. As a beginner, you don’t need to master it right away, but knowing it exists is important.
