A single use-case diagram can model a particular functionality of the system. A Use-case diagram models the actors, the system, and their interaction. These internal or external agents are known as Actors. This implies that some internal or external factors must influence the system’s behavior during run time and make it dynamic in nature. The person reviews his previous flight bookings.Īs said earlier, a use case diagram models the system’s dynamic behavior.A person logs in to search for flights.Some of the use cases in this example could be, but are not limited to: The perspective in the picture is of the end-user.Ī simple example of a use-case diagram is how an end-user interacts with the airline ticket booking system. The use-case diagram explains the various use cases where an end-user can interact with the system. It is modeled to represent the outside view of the system. It highlights the high-level requirements of the system. A Use Case diagram models the system’s dynamic behavior when operating. The center topic of today’s discussion is the Use Case diagrams. Use case diagram: Focuses on the business requirements and many more.Activity diagram: Focuses on the actions from a user perspective.Sequence diagram: Focuses more on the process from a system perspective.Class diagram: Focuses more on the blueprint.There are various diagrams serving various purposes. A complete representation of the whole system or a part of it, with the help of diagrams. UML Diagrams are software that those scaled models are to the actual structure.

Isn’t it easy to understand the complete structure when modeled as a whole before your eyes? Picture those real-life scaled models of various vast architectures, such as a mall or a housing society spread across acres, placed inside nice shiny glass boxes at the reception of the structure. The whole process falls under the larger umbrella of business process modeling techniques. It is like explaining the whole software through visual representations so that it is easy to understand and weed out possible flaws and errors in the system. This approach is a diagrammatic representation of the components and processes involved in software. Unified Modelling Language is a modern approach to the conventional process of modeling and documenting software.
