activity diagram vs state diagram

December 2nd, 2020


A state chart diagram shows a state machine emphasizing the flow of control from state to state. Such a state diagram focuses on a set of attributes of a single abstraction (object, system). Your differences aren't actually that far from the truth, though. You've learned what a State Machine Diagram is and how to draw a State Machine Diagram. It is equivalent to flowchart and data flow diagram from structured development. The figure below shows a comparison of a state diagram with a flowchart. presents a series of actions or flow of control in a system similar to a flowchart or a data flow diagram Activity diagram: captures the process flow. • Purposes of activity diagram can be described as: – Draw the activity … In contrast, the Activity diagram in the Figure of the right below does not need explicit events but rather transitions from node to node in its graph automatically upon completion of activities. State machine diagram typically is used to model the possible states of a system or entities, show how state transitions occur as a consequence of events, and depict what behavior the system or object exhibits in each state. The state diagram depict (show)the state of objects as their attributes change from state to the other state. A Sequence diagram is an interaction diagram that details about the operation that is carried out. Activity Diagram adalah diagram yang menggambarkan worlflow (aliran kerja) atau aktivitas dari sebuah sistem atau proses bisnis. Required fields are marked *. You can either show the sub-graph inside of the activity state (Figure 3), or let the activity state refer to another diagram (Figure 4). It models the transitioning of states for an incident. Activity diagram is used to document the logic of a single operation/method, a single use case or the flow of logic of a business process. 2 Information Systems Analysis and Design CSC340 © 2001 Jaelson Castro and John Mylopoulos State and Activity Diagrams -- 3 State Diagram for Purchase Order Both of them are UML behavioral diagrams but have different emphases. State diagrams require that the system described is composed of a finite number of states; sometimes, this is indeed the case, while at other times this is a reasonable abstraction.Many forms of state diagrams exist, which differ slightly and have different semantics Activity vs. Statechart Diagrams. All rights reserved. The sequence diagram captures the interaction between the objects in the context of collaboration. UML activity diagrams are statechart diagrams with a few extra features that are especially useful for modeling workflows. The State Diagram • We will use the state diagram to specify the sequencing / timing behavior of objects in a class - States - Events - Transitions • Generally speaking, there should be one state diagram for every class - But this is not prescribed by UML, it allows state diagrams to describe the system at any level UML diagram that focuses on the execution and flow of the behavior of a system instead of implementation The state of an object depends on its current activity or condition. UML State machine diagram and activity diagram are both behavioral diagrams but have different emphases. To describe a system function that is represented by a use case.
