# Working with document-based data

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

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

<table data-view="cards"><thead><tr><th></th><th data-hidden data-card-target data-type="content-ref"></th></tr></thead><tbody><tr><td><strong>Scan collections</strong><br><br>Collection scans identify the fields and data types in a collection.</td><td></td></tr><tr><td><strong>Use Collection View</strong><br><br>Configure generators and collection modes.</td><td><a href="/pages/GCwZu14RRvB5QWvA5GYx">/pages/GCwZu14RRvB5QWvA5GYx</a></td></tr><tr><td><strong>Use Document View for JSON columns</strong><br><br>Assign generators to fields in JSON columns.</td><td><a href="/pages/ECML3cFwndLoP2YxJwvS">/pages/ECML3cFwndLoP2YxJwvS</a></td></tr><tr><td><strong>Assign generators to path expressions</strong><br><br>In <strong>Collection View</strong> or <strong>Document View</strong>, assign a generator to fields that match a JSONPath expression.</td><td><a href="/pages/zgxOyU7jo4MjaIkIiyBV">/pages/zgxOyU7jo4MjaIkIiyBV</a></td></tr></tbody></table>
