# Working with document-based data

For document-based data connectors - currently [MongoDB](/app/setting-up-your-database/mongodb.md) - **Database View** and **Table View** are replaced by **Collection View**. "Collection" is the term that Structural uses to refer to MongoDB collections.

For JSON columns in file connector and PostgreSQL workspaces, you can use **Document View** to view and assign generators to JSON fields.
