To illustrate dependencies between the two, use a solid line with a plain arrowhead joining the socket to the lollipop.

Inherited interfaces may be shown with a lollipop, preceding the name label with a caret symbol. ![]() A required usage dependency from a component to an interface is illustrated by a half-circle, or socket, labelled with the name of the interface, attached by a solid line to the component that requires this interface. A provided dependency from a component to an interface is illustrated with a solid line to the component using the interface from a "lollipop", or ball, labelled with the name of the interface. What is a Component Diagram A component diagram, also known as a UML component diagram, describes the organization and wiring of the physical components in. Another accepted way of presenting the interfaces is to use the ball-and-socket graphic convention. One way of illustrating the provided and required interfaces by the specified component is in the form of a rectangular compartment attached to the component element. The component diagram extends the information given in a component notation element. System administrators can use component diagrams to plan ahead, using the view of the logical software components and their relationships on the system. ![]() Programmers and developers use the diagrams to formalize a roadmap for the implementation, allowing for better decision-making about task assignment or needed skill improvements. These diagrams are also used as a communication tool between the developer and stakeholders of the system. Sequence diagrams are organized according to time. They are used to illustrate the structure of arbitrarily complex systems.Ī component diagram allows verification that a system's required functionality is acceptable. Sequence Diagram is an interaction diagram that details how operations are carried out - what messages are sent and when. In Unified Modeling Language (UML), a component diagram depicts how components are wired together to form larger components or software systems.
