Computer Services is an imaginary company we created for the purpose of
demonstrating a typical online relational database system. We can program
YOUR database to function with your own preferences.
Gil Bates, the owner, started his
computer service and installation business in 1990, and he
and his staff have made a comfortable living ever since.
Serving the greater San Diego area,
the company has a staff of field service techs equipped with Internet
enabled 3G mobile phones (pictured below) that are able to exchange data with their online
database.
There is also a dispatcher (Andrew
Fulton) who sets up the orders and monitors field requirements, a sales
person (Nancy Davies), and an office administrator (Margaret Maloney).
The diagram above is a schematic of
the system structure. The rectangle in the center represents the central
database on the Internet, and each node on the edge of the circle represents
a remote user (fill color denotes access privilege level).
