There might be scenarios when the state of the object does not change upon the occurrence of an event. Self transition – We use a solid arrow pointing back to the state itself to represent a self transition.We use the join notation when two or more states concurrently converge into one on the occurrence of an event or events. Join – We use a rounded solid rectangular bar to represent a Join notation with incoming arrows from the joining states and outgoing arrow towards the common goal state.We use the fork notation to represent a state splitting into two or more concurrent states.įigure – a diagram using the fork notation Fork – We use a rounded solid rectangular bar to represent a Fork notation with incoming arrow from the parent state and outgoing arrows towards the newly created states.A state represents the conditions or circumstances of an object of a class at an instant of time. State – We use a rounded rectangle to represent a state.The arrow is labelled with the event which causes the change in state. Transition – We use a solid arrow to represent the transition or change of control from one state to another.Initial state – We use a black filled circle represent the initial state of a System or a class.Basic components of a statechart diagram –

The state diagram above shows the different states in which the verification sub-system or class exist for a particular system. However, a flowchart on the other hand portrays the processes or commands that on execution change the state of class or an object of the class.įigure – a state diagram for user verification The basic purpose of a state diagram is to portray various changes in state of the class and not the processes or commands causing the changes. So, a behavior diagram simply guides us through the functionality of the system using Use case diagrams, Interaction diagrams, Activity diagrams and State diagrams.ĭifference between state diagram and flowchart – They are used to model and construct the functionality of a system. Behavior diagram – Used to model the dynamic change in the system over time.Structure Diagrams – Used to model the static structure of a system, for example- class diagram, package diagram, object diagram, deployment diagram etc.Design Patterns | Set 2 (Factory Method).Singleton Design Pattern | Implementation.SDE SHEET - A Complete Guide for SDE Preparation.Difference between Inverted Index and Forward Index.Introduction of Relational Model and Codd Rules in DBMS.Generalization, Specialization and Aggregation in ER Model.Conceptual Model of the Unified Modeling Language (UML).Unified Modeling Language (UML) | An Introduction.Unified Modeling Language (UML) | Object Diagrams.Unified Modeling Language (UML) | Activity Diagrams.Unified Modeling Language (UML) | State Diagrams.Unified Modeling Language (UML) | Sequence Diagrams.Unified Modeling Language (UML) | Class Diagrams.ISRO CS Syllabus for Scientist/Engineer Exam.ISRO CS Original Papers and Official Keys.GATE CS Original Papers and Official Keys.
