If you’re familiar with SQL and new to using the BI tool Looker, here are the basics to build a mental model of Looker’s data modelling components.
Explores are similar to a SQL query. Explores join views together; and define the fields available for selection.
Models are similar to a database connection; there is one connection per model. Models group explores together.
Projects group all the view, model, and explore LookML definition files together. A project is managed inside a single git repository. Projects can be connected to each other in order to share their content.
