No two lifeline notations should overlap each other. A Quick Overview of the Various Parts of a Sequence Diagram Lifeline NotationĪ sequence diagram is made up of several of these lifeline notations that should be arranged horizontally across the top of the diagram. Each object has a column and the messages exchanged between them are represented by arrows. Sequence Diagram NotationsĪ sequence diagram is structured in such a way that it represents a timeline that begins at the top and descends gradually to mark the sequence of interactions. They can be used to model both simple and complex interactions between objects, making them a useful tool for software architects, designers, and developers. Sequence diagrams are commonly used in software development to illustrate the behavior of a system or to help developers design and understand complex systems. In simpler words, a sequence diagram shows how different parts of a system work in a ‘sequence’ to get something done. They illustrate how the different parts of a system interact with each other to carry out a function, and the order in which the interactions occur when a particular use case is executed. Sequence diagrams, commonly used by developers, model the interactions between objects in a single use case.
Among the three, sequence diagrams are preferred by both developers and readers alike for their simplicity.
These diagrams are used to illustrate interactions between parts within a system. There are 3 types of Interaction diagrams Sequence diagrams, communication diagrams, and timing diagrams.
