# Data Dictionary App

The Data Dictionary app provides access to a list of all available fields in your workspace, including calculated fields, such as calculated dimensions and measurements. Use this app to understand how fields are built and how they relate to your data.

If you’re an admin, create and update data field definitions, and then share the app with viewers and power users so that they can analyze the data. This app doesn’t create, update, or install any underlying entities. It also doesn’t automatically filter out any fields based on user restriction.

Here’s a video about the Data Dictionary app:
