The IMAGE/SQL environment requires a TurboIMAGE/XL database that may or may
not have an existing application to support it.
If your site already
has TurboIMAGE/XL databases, your design work is already done for you. To
describe the concepts of IMAGE/SQL, a TurboIMAGE/XL database must be defined.
The application presented in this chapter
is a simple demonstration of some key
IMAGE/SQL features. The design is not sophisticated. Database design is
the subject of much theoretical discussion and debate, but performance
and flexibility usually surface as desired results. The database design
presented here may not provide either, but it does demonstrate some key
points of IMAGE/SQL.
