The Catalog is where you will find all your data! Every extracted table end up stored there, transformations use data from it as input and store the output tables there. Destinations and visualizations consume data from your catalog too. It’s the core of everything.

The existing tables can be seen there, organized as you defined. At the data storage level, they are organized across Layers. For visual organization, tables can be allocated into folders.

As soon as you configure a source, you’ll see the tables already created on the catalog, altough they might be without data. That’s expected and only mean your tables are ready to receive data. Just make sure your source has at least one successful run (either trigger it manually or wait for the defined automatic trigger) and the tables should be filled with your updated data.

In a table’s overview, you can see the its list of columns and some metadata such as size, total number of rows, date of last update and creation, and a link to the source that generates it.

The Catalog is the place to have an overview of all your data and brings the correct feeling of having control over everything in a single place.
