Data Modeling - (Metadata|Descriptor)

1 - About

Metadata are data about data. They are data that describes other data.

Metadata is information stored in the data dictionary about components of the data model.

A similar yet earlier term for metadata is “ancillary data.” The prototypical example of metadata is the library catalog, which is a description of the contents of books.

In the SQL specification, they write that the descriptor of an object represents everything that needs to be known about the object.
