A nested state diagram is used to model the complex system as the regular state diagram is inadequate in describing the large and complex problem. The nested state diagram is the concept of advanced state modelling. Conventionally a complex system has much redundancy. This redundancy can be resolved by restructuring the complex system. One method to restructure complex … [Read more...] about Nested State Diagram
State Model
A state model describes the timely behaviour of the class objects over a period of time. A state model has multiple state diagrams where each state diagram describes a class in the model. State model shows these changes in the object with the help of states, events, transitions and conditions. Events are the incidents that occur to the object at a particular time whereas the … [Read more...] about State Model
Multiple Inheritance in Object Orientation
Multiple inheritance in object orientation is a form of generalization which allows a class to inherit features from multiple super class. Using the concept of multiple inheritance, you can derive an object that incorporates the information from multiple classes. Multiple inheritance elevates the potential of programming languages and increases the possibility of reusing the … [Read more...] about Multiple Inheritance in Object Orientation
Aggregation in Object Orientation
Aggregation in object orientation is a kind of association which relates two objects by ‘part-of whole’ relationship that’s why it is possible only in a binary association. Aggregation is a ‘has-a’ relationship between two class like a car has a wheel, an engine has a gearbox and so on. Discovering aggregation in a class model is just a matter of judgement. In this section, … [Read more...] about Aggregation in Object Orientation
Link and Association
Link and association in UML represent the relation between objects and classes. Link is used to establish the relation between the objects in the object diagram. Association is used to represent the relation between the classes. In the problem statement provided to develop the software, link and association are presented by the verb. In this section, we will be discussing … [Read more...] about Link and Association
