# Types of views in the Data Viewer

There are four views in the Data Viewer.

- Summary View—Provides summary data counts across multiple form types, grouped by visits or sites.
- Record Listing View—Provides a display of clinical data per form that can span across sites, subjects, and visits, or provides a display of data from multiple clinical forms in one view.
- Record Comparison View—Provides a side-by-side comparison of two Record Listing Views.
- Comments View—Provides a list of form and item comments for all sites, visits, and forms.

The user interface for each view uses the same toolbar, filter, pagination, and column customization features. For more information, see Common Data Viewer features.

Note: The Data Viewer supports blinded data and display overrides. Data that is blinded to the user does not appear in any of the Data Viewer views.
