What is ref in sequence diagram?
What is ref in sequence diagram?
ref Reference: refers to an interaction defined on another diagram. The frame is drawn to cover the lifelines involved in the interaction. You can define parameters and a return value.
What is Sequence diagram explain with example?
A sequence diagram is a Unified Modeling Language (UML) diagram that illustrates the sequence of messages between objects in an interaction. For example, lifelines in a sequence diagram for a banking scenario can represent a customer, bank teller, or bank manager.
What is lifeline OOSE?
Lifelines. A lifeline represents an individual participant in a sequence diagram. A lifeline will usually have a rectangle containing its object name. Sometimes a sequence diagram will have a lifeline with an actor element symbol at its head. This will usually be the case if the sequence diagram is owned by a use case.
What tool is used for sequence diagrams?
A sequence diagram can also be made with Lucidchart. Users can draw various visual illustrations, from simple to technical diagrams. And like GitMind, this sequence diagram tool can improve the creation process with its collaboration feature.
What is the sequence diagram in enterenterprise architect?
Enterprise Architect has a full and rigorous implementation of the Unified Modeling Language static and dynamic diagrams including the Sequence diagram. These diagrams are useful for a range of purposes where the Classifiers (or Instances) that participate in achieving an outcome interact together, sending and receiving messages.
What is an example of a sequence diagram?
Sequence Diagram with References An example of a Sequence diagram showing the Objects defined in a Use Case. Two Fragments have been used that provide a reference to other diagrams depicting other parts of the Use Case. These Fragments provide simple references to complex diagrams ensuring the current diagram does not become large and cumbersome.
What is a diagram gate?
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.
What is the CSA enterprise architecture?
The CSA Enterprise Architecture was adopted by the National Institute of Standards and Technologies in NIST SP 500-299 and NIST SP 500-292. This diagram provides a broad overview and visual representation of the Enterprise Architecture. It is intended as your quick reference guide.
