It is essential to analyze the whole system before starting with drawing a use case diagram, and then the system's functionalities are found. It represents the interaction between the actors. ![]() It recognizes the internal as well as external factors that influence the system.It depicts the external view of the system.It represents how an entity from the external environment can interact with a part of the system.įollowing are the purposes of a use case diagram given below: It invokes persons, use cases, and several things that invoke the actors and elements accountable for the implementation of use case diagrams. It accumulates the system's requirement, which includes both internal as well as external influences. The main purpose of a use case diagram is to portray the dynamic aspect of a system. It depicts the high-level functionality of a system and also tells how the user handles a system. It models the tasks, services, and functions required by a system/subsystem of an application. It encapsulates the system's functionality by incorporating use cases, actors, and their relationships. Design: .A use case diagram is used to represent the dynamic behavior of a system. Modeling with Composite Structure Diagram.Creating Element by using ShortCut Generation Syntax.Element Management by Models, Subsystems and Packages.It is included in interaction point with other parts of system. ![]() The elements that constitute software components and the elements that implement those components can all be expressed by Component Diagram.ĭeployment Diagram expresses the hardware elements of the physical computer and devices and the software components, processes and objects that are assigned to them.Ĭomposite Structure Diagram is a diagram to express internal structure of Classifier. Activity Diagram is commonly used for expressing workflow, and it is frequently used for objects like classes, packages, and operations.Ĭomponent Diagram expresses the dependency between the software components. Although Statechart Diagram is generally used to express the behaviors for instances of classes, it can also be used to express behaviors of other elements.Īctivity Diagram is a special form of Statechart Diagram that is suitable for expressing the activity execution flow. Statechart Diagram expresses the static behaviors of a specific object through states and their transitions. While Collaboration Diagram is an Instance-oriented expression, Collaboration Role Diagram is a ClassifierRole-oriented expression. It is a direct expression of the collaboration model of the ClassifierRoles within a Collaboration. While Collaboration Role Diagram is a ClassifierRole-oriented expression, Collaboration Diagram is an Instance-oriented expression.Ĭollaboration Role Diagram expresses the collaboration between the role concepts. It is a direct expression of the collaboration model of the instances within a CollaborationInstanceSet. While Sequence Diagram is an Instance-oriented expression, Sequence Role Diagram is a ClassifierRole-oriented expression.Ĭollaboration Diagram expresses the collaboration between instances. It is a direct expression of the Interaction, which is a set of the messages exchanged between the ClassifierRoles within a Collaboration. Sequence Role Diagram expresses the interactions of the role concepts. While Sequence Role Diagram is a ClassifierRole-oriented expression, Sequence Diagram is an Instance-oriented expression. It is a direct expression of the InteractionInstanceSet, which is a set of the stimuli exchanged between the instances within a CollaborationInstanceSet. Sequence Diagram expresses the interactions of instances. Use Case expresses the functions of the system and how the system functions interact with the external actors. Use Case Diagram is an expression of relations between the use cases in a specific system or object and the external actors. ![]() ![]() Class Diagram can contain not only classes but also interfaces, enumerations, packages, various relations, instances, and their links. Class Diagram is a visual expression of various static relations of class-related elements.
