Data Modeling - (Metadata|Descriptor)
1 - About
Metadata are data about data. They are data that describes other data.
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.
