Dear Rhoni: I'm Being Harassed and Bullied by an AFF pos[t]er

My usage is usually in the context of: the data "in the database", "on the hard drive", etc. or "The data is most likely intact". My "personal" definition of data is that it is a concept (and a concept is singular)... even though that is probably still incorrect. For me, data is a concept, meaning a collection of files, etc. intended to be used for a specific function.
