This document discusses the Media class and MediaDAO class used for storing media data in a database. The Media class defines fields for the media id, filename, date, role, mime type, visibility, owner, and data. The MediaDAO class is used to transfer data between the Media entity and database. It includes fields for each property in Media and methods for getting and setting the field values.
