Spatial information, either by itself or in combination with traditional relational database management system output, can help you to design projects and make business and policy decisions. For example, suppose that the manager of a county welfare district needs to verify which welfare applicants and recipients actually live within the area that the district services. Spatial Extender can derive this information from the service area's location and from the addresses of the applicants and recipients.
Or suppose that the owner of a restaurant chain wants to do business in nearby cities. To determine where to open new restaurants, the owner needs answers to such questions as: Where in these cities are concentrations of clientele who typically frequent my restaurants? Where are the major highways? Where is the crime rate lowest? Where are the competition's restaurants located? DB2 Spatial Extender can produce spatial information in visual displays to answer these questions, and the underlying relational database management system can generate labels and text to explain the displays.
