UML Diagrams

UML Diagrams 
  • Use case diagram
  • Class diagrams
  • Interaction diagram
  • State diagram
  • Activity diagram
  • Component diagram
  • Deployment diagram

Use case diagram 
  • Displays the relationship among actors and use cases
Class diagram 
  • It models both class structure and contents by making use of design elements such as 
Interaction diagrams
Sequence diagram 
  • It displays the time sequence of the objects participating in the interaction 
  • The diagram has a vertical dimension which represents time and a horizontal dimension which represents different objects 
Collaboration diagram 
  • It displays an interaction organized around the objects and their links to one another 
  • The sequence of messages is represented in terms of numbers 

State diagram 
  • It displays the sequences of states that an object of an interaction goes through during its life in response to received stimuli, together with its responses and actions. 
Activity diagram 
  • It displays a special state diagram in which almost all the states are action states and most of the transitions are triggered by completion of the actions in the source states 
  • This diagram focuses on flows driven by internal processing 
Component diagram 
  • It displays the high level packaged structure of the code 
  • It also shows the dependencies among different components, which include 
  • ⃝source code components 
  • ⃝binary code components, and 
  • ⃝executable components 
  • Some components exist at compile time, at link time, at runtimes as well; more than one time 
Deployment Diagram 
  • It displays the configuration of 
  • elements and software components involved in the runtime processing 
  • ⃝processes 
  • ⃝objects that live on them 
  • Software component instances represent runtime manifestations of code units
