![]() This means that StarUML now considers the classes to be part of the package. But don't be disappointed look at the model explorer and you'll see that the classes now are under the package: When you release the mouse for the drop, the classes will move by translation, but the package symbol remains unchanged, giving the impression of a failed operation. But caution: it is not sufficient to move the classes around until some overlap the package: you really have to drag the mouse into the package, so that StarUML gives you a visual feedback with the package element surrounded by a highlighting frame (in blue in my screenshot): Now I can select the 3 classes and drag and drop them into the package. Here the result look especially at the model explorer that shows the classes and the package at the same level: I have created 3 classes (note the automatic names Class 1, Class 2, Class 3, the next would be Class 4) and then a package. web server, mail server, application server) are presented as nodes, with the software components that run inside the hardware components presented as artifacts.The answer is that moving several classes to a package probably already assigned the classes to the package, but that visually, the package symbol is just no enclosing them. In deployment diagram, hardware components (e.g. Models the physical deployment of software components with UML deployment diagram. Objects implementing a required interface are received via a port and objects implementing a provided interface are shared via a port.Ĭomponent Diagram Example - Components in Deployment Diagram.Ports are shown as squares bordering the component, these indicate how the interfaces of the component are used internally. ![]() In this example, the internal composition of components can also be modeled using component diagrams, this is called a white-box view of the diagram because we can see inside. Objects implementing a required interface are received via a port and objects implementing a provided interface are shared via a port. Ports are shown as squares bordering the component, these indicate how the interfaces of the component are used internally. In the previous examples, those component diagrams are called black-box views. The Figure below show's the Store's component nested structure.Ĭomponent Diagram Example - White-Box View of a Component To show a nested component structure, you merely draw the component larger than normal and place the inner parts inside the name compartment of the encompassing component. A component that processes credit card charges and the database containing the ticket information.Ĭomponent Example - Store Component - nested component structure There is a ticket seller component that sequentializes requests from both ticket selling system and clerks. Ticket Selling System Component Diagram Example As long as those requirements are maintained changes to one component will not percolate to other components. By using a component diagram we see the system as a group of nearly independent component or subsystems that interact with each other in a specifically defined way.Įach component is responsible for the action for which it is named and interface(s) it provides. The Figure below is a much larger view of what is involved in a online store. One main benefit of Component diagrams if to simplify the high-level view of the system. Order Processing System Component diagram example Draw subsystems for logical categorization of components. ![]()
