A sequence diagram is a form of interaction diagram which shows objects as lifelines running down the page with their interactions over time represented as messages drawn. Start a sequence diagram.

UML sequence diagrams model the flow of logic within your system in a visual manner enabling you both to document and validate your logic and are commonly used for both analysis and design purposes. Under Template Categories click Software and Database and then click UML Model Diagram. Use Lucidchart to visualize ideas make charts diagrams more.

As you can guess from its name the Sequence diagram shows the order in which interactions take place. Sequence diagrams are one of the 14 diagram types that can be created using the Unified Modeling Language UML. See how objects and components interact with each other in sequence to complete a process.

You can accomplish several critical tasks with a sequence diagram. UML sequence diagrams are used to show how objects interact in a given situation. They capture the interaction between objects in the context of a collaboration.

Class Roles or Participants Class roles describe the way an object will behave in context. It is also known as an event diagram. A sequence diagram can.

It absorbs the branching as well as iterations. A dotted vertical line can express a message and lifelines can be illustrated by a vertical bar in UML that spreads crosswise the base of a page.
