What is Sequence diagram in architecture?

A Sequence diagram is a structured representation of behavior as a series of sequential steps over time. You can use it to: Depict workflow, Message passing and how elements in general cooperate over time to achieve a result.

How do you create a Sequence diagram in EA?

In your project browser first click on the new diagram icon:

1. Then select ‘UML Behavioral’ from the type column and ‘Sequence’ from the Diagram Type column:
2. Drag an actor on to the drawing area:
3. And then a lifeline:

What is an Enterprise Architect Model?

An Enterprise Architect model is a top level (root) Package in a repository. It is possible to have more than one root Package in a repository and hence more than one model. Each model is the root node of a hierarchy of Packages, elements, features and diagrams that are nested under the Package.

What is the use of system sequence diagram?

Sequence diagrams are used to express interactions of external elements with the system realizing a use case, interesting specific interactions among elements within the system design, or specify test cases using the UML Testing Profile [2].

What is entity in sequence diagram?

An Entity is a stereotyped Object that models a store or persistence mechanism that captures the information or knowledge in a system. Entity. A Fragment element can represents iterations or alternative processes in a Sequence diagram.

What are the basic elements of a sequence diagram?

Basic Sequence Diagram Notations

• Class Roles or Participants. Class roles describe the way an object will behave in context.
• Activation or Execution Occurrence. Activation boxes represent the time an object needs to complete a task.
• Messages.
• Lifelines.
• Destroying Objects.
• Loops.
• Synchronous Message.
• Asynchronous Message.

What are elements of sequence diagram?

Key elements A sequence diagram shows, as parallel vertical lines (lifelines), different processes or objects that live simultaneously, and, as horizontal arrows, the messages exchanged between them, in the order in which they occur. This allows the specification of simple runtime scenarios in a graphical manner.

What is sequence diagram with example?

A sequence diagram shows the sequence of messages passed between objects. Sequence diagrams can also show the control structures between objects. For example, lifelines in a sequence diagram for a banking scenario can represent a customer, bank teller, or bank manager.

What are the six basic elements of Enterprise Architecture?

What are the six basic elements of enterprise architecture?

• Architecture management. Each enterprise will need an oversight team for the architecture.
• Architecture framework.
• Implementation methodology.
• Documentation artifacts.
• Architecture repository.
• Associated best practices.

What are the key concepts of Enterprise Architecture?

In the case of Enterprise Architecture, these models describe the logical business functions or capabilities, business processes, human roles and actors, the physical organization structure, data flows and data stores, business applications and platform applications, hardware, and communications infrastructure.

What is the objective of sequence diagram?

The diagram’s purpose The sequence diagram is used primarily to show the interactions between objects in the sequential order that those interactions occur. Much like the class diagram, developers typically think sequence diagrams were meant exclusively for them.

How to create sequence diagram using sparxsystems Enterprise Architect?

What can you do with a sequence diagram?

A Sequence diagram is a structured representation of behavior as a series of sequential steps over time. You can use it to: Depict workflow, Message passing and how elements in general cooperate over time to achieve a result

What does a lifeline mean in a sequence diagram?

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. 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.

How to create a message in Enterprise Architect?

The Message reflects the attributes from the source Class; you cannot add further attributes to the source Class here – if no appropriate attribute is listed, open the Class element ‘Properties’ dialog and add the required attribute. Otherwise, optionally type the name of the object to assign the message flow to.
