To unlock the magic of Looker, data experts at each organization describe their data in a lightweight modeling language called LookML. LookML tells Looker how to query data, so everyone in the organization can create reports and dashboards without needing to understand the behind-the-scenes details. This page outlines the documentation on preparing to write LookML.
