It has to open the file and retrieve the database and show the relationship when the appropriate commands are issued.

The database catalog of  a database must contain metadata in which definitions of database objects such as base tables, views (virtual tables),synonyms, value ranges,indexes, users and user groups are stored

Tutor went the extra mile to help me with this essay. Citations were a bit shaky but I appreciated how well he handled APA styles and how ok he was to change them even though I didnt specify. Got a B+ which is believable and acceptable.
