The programmers and database admin have asked about the security requirements for this system. I don't think that we've discussed these requirements. I$\text{'}$d like for you to think through the classes of users $($Appointment setters, Technicians, Part Department, Management, Customers$)$ and what type of access they require. Also, how do you think we need to protect the technician's machines and the server?

Security is such an important issue now. There have been so many security breaches recently with our competitors.
