enterprise architect sequence diagram

If the diagram being generated already exists under the selected element, a prompt displays to overwrite or synchronize with that diagram. They can be used by business and technical users but are more commonly used for technical descriptions of a system.

The Sequence diagram is one of the Unified Modeling Language (UML) Behavioral diagrams that can be used to define the time ordered flow of messages between elements. Message (Sequence Diagram) Sequence diagrams depict workflow or activity over time … A few screenshots describing how to create sequence diagrams using Enterprise Architect. Sequence diagrams can also be created automatically from stack traces as a way of visualizing how a system functions.The elements that appear in Sequence diagrams can be either Classifiers such as Classes and Components or instances such as Objects and Component Instances. An Endpoint is used in Interaction diagrams to reflect a lost or found Message in sequence.A Diagram Gate is a simple graphical way to indicate the point at which messages can be transmitted into and out of interaction fragments.The State/Continuation element serves two different purposes for Sequence diagrams, as State Invariants and Continuations. A Lifeline represents a distinct connectable element and is an individual participant in an interaction.Boundary elements are used in analysis to capture user interactions, screen flows and element interactions.A Control organizes and schedules other activities and elements.An Entity is a stereotyped Object that models a store or persistence mechanism that captures the information or knowledge in a system.A Fragment element can represents iterations or alternative processes in a Sequence diagram. The following two diagrams show how they might be used in practice. There is an excellent YouTube presentation, which is where I got a lot of this information from, available from here: Enterprise Architect generates the diagram and notifies you that generation is complete. Commonly an Actor (representing a role played by a user) starts the flow and messages are passed between the elements showing how a result is achieved.Ribbon: Design > Diagram > Insert > UML Behavioral > SequenceProject Browser context menu | Add Diagram... > UML Behavioral > SequenceThe Sequence diagram can be used to model any set of messages that flow between two or more elements to produce a result. Time is by convention represented on the vertical axis and elements (Classifiers or Instances) are positioned horizontally at the top of the diagram. Diagram gates act as off-page connectors for sequence diagrams, representing the source of incoming messages or the target of outgoing messages. Note that the gate on the top level diagram is the point at which the message arrowhead touches the reference fragment - there is no need to render it as a box shape. Enterprise Architect has a full and rigorous implementation of the Unified Modeling Language static and dynamic diagrams including the Sequence diagram. Es wird festgelegt, wann ein Objekt erstellt wird und wann Nachrichten zu welchem Objekt gesendet werden.

Commonly an Actor … Time is by convention represented on the vertical axis and elements (Classifiers or Instances) are positioned horizontally at the top of the diagram.

You can use an Interaction element to insert an Interaction diagram as a child of a Class element. You can use it to: Depict workflow, Message passing and how elements in general cooperate over time to achieve a result Fragments can also be added to represent control structures that operate on a group of messages. A Message indicates a flow of information or transition of control between elements.A Self-Message reflects a new process or method invoked within the calling lifeline's operation.A Recursion is a type of Message used in Sequence diagrams to indicate a recursive function.A Call is a type of Message connector that extends the level of activation from the previous Message. You can use it to:To toggle the numbering of messages on a Sequence diagram, select or deselect the 'Show Sequence Numbering' checkbox on the 'Preferences' dialog.You generate Sequence diagram elements and connectors from the 'Interaction' pages of the Toolbox.This example Sequence diagram demonstrates several different elements.An Actor is a user of the system; user can mean a human user, a machine, or even another system or subsystem in the model.

The Sequence diagram is one of the Unified Modeling Language (UML) Behavioral diagrams that can be used to define the time ordered flow of messages between elements. The choice will depend on what the modeler wants to represent.

Click on the OK button and then close the 'Properties' dialog to review the diagram. Die Reihenfolge der Nachrichten entspricht ihrer horizontalen Position im Diagramm. A Sequence diagram is a structured representation of behavior as a series of sequential steps over time. They are more typically used by technical modelers to depict how messages are passed between application components and interfaces to achieve an outcome. Click on the type of diagram to generate.
