Activity model is the activity diagram which expresses the sequence of steps required to form a complex process. The activity diagram displays the flow of control like the conventional flow chart but is considered as the more advance version of it. The activity diagram is similar to the sequence diagram as we have seen in our previous content. But, unlike a sequence diagram, … [Read more...] about Activity Model

A sequence model elaborates a use case and describes the interaction between the objects in a sequence over a period of time. Sequence model conceptualizes the interaction between the objects by displaying the exchange of messages between them over time. The sequential model describes how the system parts interact to execute a use case and get a function done. In this … [Read more...] about Sequence Model

Use case model is a high-level abstraction of the interaction model. Use case model defines how the users interact with a system and what functional behavior does the system offers to its users. Use case model shows the graphical representation of how a user interacts with the system to get a solution to a particular problem for which the system is designed. In this section, … [Read more...] about Use Case Model

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

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
