Chapter 2 Planning and Defining Your Application Working with HP ALLBASE/4GL HP ALLBASE/4GL does not place many restrictions on the way you can develop applications, apart from the need to define dictionary items before they can be used in other parts of the application. Typically, developing an application with HP ALLBASE/4GL involves five phases: * Phase 1--Application planning. * Phase 2--Data definition. * Phase 3--Screen development. * Phase 4--Logic definition. * Phase 5--Report definition. These phases represent one of many possible approaches to application development using HP ALLBASE/4GL. We will examine each one in turn as you develop the sample application. Each phase and task you perform includes an explanation to aid you in understanding its purpose. For more detailed information about any of the phases or the tasks they require, refer to your HP ALLBASE/4GL Developer Reference Manual.
