First, I want to ask, what is the definition of metadata? Then, what is the difference between metadata and schema in the database? Does the data modeling process create metadata?

A schema is a layout of your database. For example, table fields, definition, pages, rows and columns, etc.

Metadata is data about your database. For example, if you have data on all rap music, your metadata will be: Author, Number of Tracks, Release Year, Location, Album Name, etc.
