Components Diagram (UML)

Modelação 10

• A Component Diagram illustrates the pieces of software, embedded controllers and such that make up a system, and their organization and dependencies.

• 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. They are building blocks, built up so that eventually a component can encompass a large portion of a system.

The dependencies among software systems’ components can be expressed in components diagrams:

• Source code• Binary code• Executable code• Business processes…• Documents…• …

Interfaces in Components

“Interfaces” are important to support replacement and re-usage...

• A component initially designed for one specific system can be reused in another system…

• A component can be replaced by other component…

• Assembly connectors link the provided interfaces supplied by Product and Customer to the required interfaces specified by Order.

• A Dependency relationship maps a customer's associated account details to the required interface Payment, indicated by Order.

Components can contain other components…

Deployment Diagrams

16Modelação

• A Deployment diagram shows how and where the system is to be deployed; that is, its execution architecture.

• Hardware devices, processors and software execution environments (system Artifacts) are reflected as Nodes, and the internal construction can be depicted by embedding or nesting Nodes.

• As Artifacts are allocated to Nodes to model the system's deployment, the allocation is guided by the use of deployment specifications.

• A hardware node

• A software application

• A specification (document)

• A software component

Modelação 18Retirado do “Help” do Enterprise Architect

Deployment Diagram (example)

• Two Nodes have a TCP/IP communication path indicated.

• Deployment relationships indicate the deployment of Artifacts. Furthermore, a deployment spec defines the process of deployment for the networkScanner Artifact.

• The Manifestation relationships reveal the physical implementation of components ReposCustomer and ReposInternalRecords.

Nodes and Components

• Both can have instances…

• But– Components are things that take part in the execution of a system

– Components represent groups of logical elements• While

– Nodes represent the physical deployment of components
