The following diagram details a component with a port for online services along with two provided interfaces order entry and tracking as well as a required interface payment. Ports may specify inputs and outputs as they can operate bi-directionally. Using Ports with component diagrams allows for a service or behavior to be specified to its environment as well as a service or behavior that a component requires. The assembly connector bridges a component’s required interface (Component1) with the provided interface of another component (Component2) this allows one component to provide the services that another component requires. With component diagrams all of the model elements are private, whereas package diagrams only display public items.Ĭomponents are represented as a rectangular classifier with the keyword «component» optionally the component may be displayed as a rectangle with a component icon in the right-hand upper corner. The difference between package diagrams and component diagrams is that Component Diagrams offer a more semantically rich grouping mechanism. A dependency relationship maps a customer's associated account details to the required interface "Payment", indicated by "Order".Ĭomponents are similar in practice to package diagrams, as they define boundaries and are used to group elements into logical structures. Assembly connectors "link" the provided interfaces supplied by "Product" and "Customer" to the required interfaces specified by "Order". The diagram above demonstrates some components and their inter-relationships. Easily draw UML diagrams with an online UML software that features powerful UML diagramming tools, on-the-fly UML syntax checks and a neat user interface. They are building blocks so a component can eventually encompass a large portion of a system. A component diagram has a higher level of abstraction than a Class Diagram - usually a component is implemented by one or more classes (or objects) at runtime. The interaction between the applications can be shown using a combination of Ports and Provided or Required Interfaces that describe how the Components are wired together.Ĭomponent diagrams can be drawn at a number of levels of formality, from simple diagrams that show the dependencies between Components to sophisticated diagrams using Ports, Interfaces and Information flows.UML 2 Tutorial - Component Diagram Component DiagramsĬomponent diagrams illustrate the pieces of software, embedded controllers, etc., that will make up a system. Component Diagram: Component Diagram expresses the dependency between the software components. Without a doubt, Visual Paradigm Online is the best UML Diagram software to create UML Component Diagrams. Our UML Diagram tool comes with a full set of UML symbols and connectors. Application Architectures often use a number of Component diagrams to describe the architecture of the applications and how they interact. Design system component architectures with VP Onlines powerful UML Component Diagram tool. The last version under this brand was called Agora Plastic 2005 and was published by the Korean company Plastic. 2 The version 1.1 published in 1998 dropped the OMT to support in favour of UML. Plastic 1.0 was published in 1997 to support the OMT notation. A Model is an element that contains information. StarUML is the successor of an object oriented modelling software called Plastic. Class Diagram, Component Diagram, Composite Diagram : Enumeration: Creates an enumeration element in the current diagram. The Component diagram can be used to model logical or physical parts of a system including current and future state Components. StarUML makes a clear conceptual distinction between models, views and diagrams. Project Browser context menu | Add Diagram. To edit the sequence Composite Structure Diagram - Class Diagram - StarUML documentation. Project Browser Toolbar : New Diagram icon > UML Structural > Component The sequence diagram is shown inside the Interaction Frame. Ribbon: Design > Diagram > Insert > UML Structural > Component to communicate the software architecture of a software system using diagrams and youll. The Components can be given a name, detailed descriptions can be added and additional properties can be added using Tagged Values. System landscape diagram Dynamic diagram Deployment diagram. In UML, the lifeline is represented by a. It portrays the communication between any two lifelines as a time-ordered sequence of events, such that these lifelines took part at the run time. It helps in envisioning several dynamic scenarios. Component hierarchies can be created that show how top levels systems or applications are broken down to lower level Components. The sequence diagram represents the flow of messages in the system and is also termed as an event diagram.
