ProjeQtOr - by: dabernate

I have one question:

I need to know the relational model of the ProjeQtOr application,
I was doing reverse engineer to the database made by ProjeQtOr
on the mysql Server, but I could not to see relations between the
tables.

I want to know if you have a relational model of the ProjeQtOr application
database, or if definitely ProjeQtOr has not a relational model for the database.
