Metadata

Metadata is data about data (🤯). It’s a term that developers use to describe higher level data about something, but not that thing itself. A picture, for example, is a bunch of data (pixels). But when and where that picture was taken is metadata. The same thing is true for an entire set of data: a table in a database with entries about your users is a bunch of data, but how large that table is, or what permissions different developers have for it, that’s metadata.
