Lucidchart Uml Sequence Diagram

In Lucidchart, creating a sequence diagram from scratch is surprisingly simple. Just follow these steps: Open a blank document or start with a template. How to use LucidChart to draw UML class diagrams.

Uml Sequence Diagram Tutorial

In this step-by-step tutorial, we'll show you how to make a UML sequence diagram using Lucidchart. Sequence diagrams are a type of Unified Modeling Language. Online Examination System – Class Diagram (UML) Sequence Diagram Example of a School Management System. Example of an Option Combination Fragment. Example of a Loop Sequence. Here are some more sequence diagram templates and examples that you can edit right away. Sequence Diagram Tutorial – SlideShare Presentation. Sequence diagram is the most common kind of interaction diagram, which the following nodes and edges are typically drawn in a uml sequence diagram: You draw the deletion message as an arrow, with the title (this is optional). To build a sequence diagram, use a uml sequence template or starter diagram, which includes the uml sequence stencil.

Actor a type of role played by an entity that interacts with the subject (e.g., by exchanging signals and data) external to the subject (i.e., in the sense that an instance of an actor is not a part of the instance of its corresponding subject). represent roles played by human users, external hardware, or other subjects. Note that: An actor does not necessarily represent a specific physical entity but merely a particular role of some entity A person may play the role of several different actors and, conversely, a given actor may be played by multiple different person.

Activations A thin rectangle on a lifeline) represents the period during which an element is performing an operation. The top and the bottom of the of the rectangle are aligned with the initiation and the completion time respectively
Call Message A message defines a particular communication between Lifelines of an Interaction. Call message is a kind of message that represents an invocation of operation of target lifeline.
Return Message A message defines a particular communication between Lifelines of an Interaction. Return message is a kind of message that represents the pass of information back to the caller of a corresponded former message.
Self Message A message defines a particular communication between Lifelines of an Interaction. Self message is a kind of message that represents the invocation of message of the same lifeline.
Recursive Message A message defines a particular communication between Lifelines of an Interaction. Recursive message is a kind of message that represents the invocation of message of the same lifeline. It's target points to an activation on top of the activation where the message was invoked from.
Create Message A message defines a particular communication between Lifelines of an Interaction. Create message is a kind of message that represents the instantiation of (target) lifeline.
Destroy Message A message defines a particular communication between Lifelines of an Interaction. Destroy message is a kind of message that represents the request of destroying the lifecycle of target lifeline.
Duration Message A message defines a particular communication between Lifelines of an Interaction. Duration message shows the distance between two time instants for a message invocation.

Visual Representation

Actor

a type of role played by an entity that interacts with the subject (e.g., by exchanging signals and data)
external to the subject (i.e., in the sense that an instance of an actor is not a part of the instance of its corresponding subject).
represent roles played by human users, external hardware, or other subjects.

Note that:

An actor does not necessarily represent a specific physical entity but merely a particular role of some entity
A person may play the role of several different actors and, conversely, a given actor may be played by multiple different person.

Lifeline

A lifeline represents an individual participant in the Interaction.

Activations

A thin rectangle on a lifeline) represents the period during which an element is performing an operation.
The top and the bottom of the of the rectangle are aligned with the initiation and the completion time respectively

Call Message

A message defines a particular communication between Lifelines of an Interaction.
Call message is a kind of message that represents an invocation of operation of target lifeline.

Return Message

A message defines a particular communication between Lifelines of an Interaction.
Return message is a kind of message that represents the pass of information back to the caller of a corresponded former message.

Self Message

A message defines a particular communication between Lifelines of an Interaction.
Self message is a kind of message that represents the invocation of message of the same lifeline.

Recursive Message

A message defines a particular communication between Lifelines of an Interaction.
Recursive message is a kind of message that represents the invocation of message of the same lifeline. It's target points to an activation on top of the activation where the message was invoked from.

Create Message

A message defines a particular communication between Lifelines of an Interaction.
Create message is a kind of message that represents the instantiation of (target) lifeline.

Destroy Message

A message defines a particular communication between Lifelines of an Interaction.
Destroy message is a kind of message that represents the request of destroying the lifecycle of target lifeline.

Duration Message

A message defines a particular communication between Lifelines of an Interaction.
Duration message shows the distance between two time instants for a message invocation.

Note

A note (comment) gives the ability to attach various remarks to elements. A comment carries no semantic force, but may contain information that is useful to a modeler.
