Looker is a data platform that helps developers and businesses explore, visualize, and understand their data. It turns large amounts of raw data into useful charts, dashboards, and reports that people can use to make better decisions. LookML is the special language used inside Looker to define how data is organized and connected, so it’s easier to work with.
For developers, learning Looker and LookML means they can create custom data experiences for users—like interactive dashboards or tailored reports—without needing to rewrite code every time. It allows teams to share insights across departments and make sure everyone is working with the same accurate information. It’s a powerful way to turn complex data into something clear and useful.
