Do you think I can:
1- modify "db.db" structure
2- add a data table linked to "db.db"
in order to store client information linked to flight information, etc...

1. The assignment description states :

The suncertify/db directory in this distribution also contains your database file, "db.db". You may not modify this file, but you may move it if you wish.

So no, you cannot change the structure of db.db.
2. You can add tables. But it's not asked in the assignment, so I would avoid to do it. It can only give you more space for errors ...
Hope this helps
I agree. Here's the link:
