"Area of interest" (AOI) means a spatial region, defined either by the client or the server (i.e. in a game). Typically, it's all objects that are near you. Restricting your view by AOI is an optimization to avoid downloading all of the world at once. In a game situation it also prevents players from being able to magically see for hundreds miles, unless of course they have the super radar or magic crystal ball. So it's more like SELECT * where distance_from_me <= users_view_distance. The main difference between doing SQL queries and VOS is that I think the general consensus is that a view is a predefined persistent state, represented or created by a preexisting Vobject that a client can access.
