The diagram is a picture of the system, actors, and use cases. When it comes to drawing use case diagrams one area many struggles with is showing various relationships in use case diagrams. A use case diagram should represent all interactions with the use case. USE CASE• a use case is a list of steps, typically defininginteractions between a role (actor) and asystem, to achieve a goal.• The actor can be a human or an externalsystem.• the relationships between all (or a set of) theuse cases and actors are represented in a UseCase Diagram 8. A use case model consists of a use case diagram and narrative text detailing the use cases. They are behavioral diagrams which are consist of functionality (dynamic behaviors) of a system. Specific flow of events and choices A state diagram shows the actual changes in state, not the processes or commands that created those changes. For a really complicated problem, you would use flowcharts first, then use case diagram. Purpose of Statechart Diagrams. Sequence diagrams can be based on either a use case or a scenario Can represent a use case with a more general flow of events, usually the "main" flow. Typically, Use Cases are related to the interactions between people and systems. A process flowchart will usually be a graphical representation of how a business object like an order will flow through various business rules and system states. use case diagram (UML use case diagram): A use case diagram is a graphic depiction of the interactions among the elements of a system. The most frequently used ones in software development are: Use Case diagrams, Class diagrams, and Sequence diagrams. When documenting requirements, you would create a state chart for a business object, in this example, a customer-order. In software development, it is generally used to describe the flow of different activities and actions. Activity diagram explained in the next chapter, is a special kind of a Statechart diagram. Note that: What is the difference between a use case model and a use case diagram? What is the Difference between a State Diagram and a Flowchart? A use case diagram should describe at least a single module of a system. An example of a use-case diagram A flowchart illustrates processes that are executed in the system that change the state of objects. As you can see, use case diagrams belong to the family of behavioral diagrams. Can't really capture all variations with this; Easier to represent a scenario -- a single example of the general use case. Activity Diagram. Statechart diagram is one of the five UML diagrams used to model the dynamic nature of a system. This article will look into various use case diagram relationships in detail and explain them using examples. The figure below shows the UML diagram hierarchy and the positioning of the UML Use Case Diagram. If the use case diagram is large, then it should be generalized. In fact many tend to confuse <>, <> and generalization. It contains the system boundary, called a boundary box, the actors, and the use cases. If there are too many use cases or actors, then only the essential use cases should be represented. As said, a use case diagram should be simple and contains only a few shapes. UML 2.0 statecharts, also known as state-machine diagrams and state transition diagrams, are designed to show how an object can change its state of being over time. If yours contain more than 20 use cases, you are probably misusing use case diagram. As Statechart diagram defines the states, it is used to model the lifetime of an object. Activity diagrams are probably the most important UML diagrams for doing business process modeling. They show how the users (actors) expect to interface with and get a benefit from the system through use cases (think user stories with more details). Class Diagram vs Use Case Diagram UML Use case diagrams represent the “requirements” of the system. About the first question: Use case diagram shows the interaction between the actors outside of the system you develop and the system itself. USE CASE DIAGRAM• It is a UML diagram.•
