Component and Deployment

Review State Diagrams represent the software entities in terms of their states Sequence diagram give the visual description of the sequence of the events that happen within the software entities being developed Collaboration Diagrams illustrate the communication between objects Activity Diagrams present the activities within the software entities. This presents a pictorial view of the flow of events that happens within the system being developed OOAD with UML / Session 9 / 2 of 17

Nodes Run-time physical object that represents a computational resource, generally having at least a memory and often processing capability as well OOAD with UML / Session 9 / 8 of 17

What is deployment diagram? Allow the capturing of the topology of the system nodes, including the assignment of run-time elements to nodes Allows to visually see potential bottlenecks Formed by Nodes, connections (Shown with stereo types) and components OOAD with UML / Session 9 / 9 of 17

Summing up UML OOAD with UML / Session 9 / 16 of 17

Summary Component and Deployment diagrams are Structural Diagrams in UML Component diagrams show the physical placement of the components in the system Deployment diagrams show the interconnection of the hardware and software components Rational Rose, Visual UML and Microsoft Visio are major tools to create deployment diagrams. Rational Rose is comparatively used more. Rational Rose is an complete Software Engineering tool. OOAD with UML / Session 9 / 17 of 17
