A Single Record REAd list will show the complete data of a single record in your dashboard instead of a list of records.
This view is useful for a configuration / settings table, or user preferences, ... in brief, any table that has only a single to show.
A database sometimes uses a table that will only contain a single record, which cannot be deleted. The most common example is a configuration table, or user settings.
In this case it is more appropriate to display all preferences in the admin panel on a single page.
