A component diagram in UML gives a bird’s-eye view of your software system. Dependencies are marked with a dashed line with an arrow. Deployment diagram is a structure diagram which shows architecture of the system as deployment (distribution) of software artifacts to deployment targets. The creation of UML was originally motivated by the desire to standardize the disparate notational systems and approaches to software design. You should use the same notation on interaction overview diagrams that you would see on an activity diagram. We use class diagrams to depict the static structure of a system by showing system’s classes,their methods and attributes. Which of the following UML diagrams has a static view? The activity can be described as an operation of the system. Class diagrams are the only diagrams which can be directly mapped with object-oriented languages and thus widely used at the time of construction.UML diagrams like activity diagram, sequence diagram can only give the sequence flow of the application, however class diagram is a bit different. Works on your Mac or any other device. Component Diagram
