Assignment 3: Implementation
Implement all the interactions described in assignment 2 (login,
logout and the 2 interactions depending on your group).
You may want to populate certain tables you didn't populate yet (book and author mainly).
IMPORTANT: Transactions have the ACID property.
Your implementation must either be accessible through the web or you
will have to do a demonstration.
You have to give back all the project parts with your improvements,
explanations and all your code (+ the old parts) in a binder. Provide a disk with
all the code (attach it to the binder).
