| Abstract:
The main features of an object-oriented analysis method, Object Modelling Technique (OMT), are presented and illustrated through kiwifruit orchard management examples. OMT proposes graphical representations of structure, sequencing of state changes that happen in response to stimuli, and data transformation in a system, through the unifying object concept. These representations are called object, dynamic, and functional. A simplified kiwifruit orchard structure exemplifies the object representation, which shows data and their structural links by means of objects and associations. Natural objects are defined, such as the grower, the climate, and the orchard viewed as an aggregation with several levels. The dynamic representation, which deals with temporal relationships, is introduced through the lifecycle of a reproductive organ, drawn as a state diagram, i.e. a pattern of states, transitions between states, and events causing transitions. For illustrating the functional representation, which uses data flow diagrams for showing data transformation, we consider simple points of view on fruit set and growth, which involve inputs and outputs and the computation of intermediate values. | |
