Yeah, that's caching, and it's great when one can do it :-)

edit: kidding aside, this is approximately what a database view is, at least in some implementations (though probably not as common as the more simple implementation): a view is created as a SQL query that pulls some data. It's stored as is. As data is inserted to the database, the views (a.k.a. queries) that would include that row are updated too.
