Such elimination would be impossible without using an external data source
of businesses now open/closed, so in my view this would constitute a
Derivative Database (with physical observations). "Adding" is an abstract
term: "removing" closed businesses could be viewed as adding information
about whether a business is now open or closed. Even if you then physically
remove all closed businesses from the database, this information would
still remain (implicitly) in the database.
