In Shepherd's Staff, a Room represents an area or location of the church where an Event may be held (every Event must be in a Room.).
Using this definition, we can see that a "Room" does not have to be an enclosed space. A room can be anything from a church narthex to an outdoor playground or ballfield. You could even use a section of an interior room which is especially helpful if a church wants to schedule future maintenance.
All of these room records are contained within the Rooms view, where you can see all the rooms you have in your database.
