Lektronica Computer
Services is an imaginary company we
created for the purpose of
demonstrating a typical online
relational database system.
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 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).
This diagram is
a schematic of the system structure.
The cog in the center represents the
central database application on the
Internet, and each node around the core represents a remote
user (colors denote specific access
privilege level).
