Understanding the Environment 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.
