  2. Description • Sequence diagrams illustrate how objects interact with each other. • They focus on message sequences, that is, how messages are sent and received between a number of objects. • Sequence diagrams have two axes: • the vertical axis shows time and • the horizontal axis shows a set of objects. • A sequence diagram also reveals the interaction for a specific scenario — a specific interaction between the objects that happens at some point in time during the system’s execution (for example, when a specific function is used).

  3. Concept of Sequence Diagram

  4. Generic and Instance Form • Sequence diagrams can be used in two forms: the generic form and the instance form. • The instance form describes a specific scenario in detail; it documents one possible interaction. The instance form does not have any conditions, branches, or loops; it shows the interaction for just the chosen scenario. • Example: student choose a list of courses for specific condition, he want to finish his study faster than normal condition • The generic form describes all possible alternatives in a scenario; therefore branches, conditions, and loops may be included. • Example: student choose a list of courses for normal condition
