• RAD offers such diagrams:

• Class: components or elements 

• Browse: to browse underlying elements, relationships (group) 

• Topic: quick way to show relationships between elements (non-editable) 

• Sequence: interactions between objects wrt sequence of messages betweeen them 

• Static Method: the cronological sequence of messages between elements in an interaction 

Building Blocks: 

• Things 

• Relationships 

• Diagrams 

Things: 

• Structural: interfaces, classes 

• Behavioral: interaction (set of messages) (represents verbs - dynamic) 

• Grouping: to organise a model 

• Annotional: provides further explanation 

Relationships: 

• Dependency: between two things (a parameter in a method) 

• Association: connection to navigate (a property as a class) 

• Extends: specialization or concretion (inheritance of a class) 

• implements: realization of operations ( implementation of an interface) 

• own: for implementation reasons and hiding info (package of a class) 

Diagrams: 

• Structural: building blocks that do not change over time (component, class diagrams) 

• Dynamic: behavior: colloborations among objs and changes in states (use case, activitiy diags.) 

• Interaction: exchange of messages (sequence diagrams) 

Use case: 

• Use case: Actor, use case, association 

• Activity diagrams: Swimlines, Activity, decisions, transition, initial, final states 

• Analysis stereotypes: boundary control, entity 

• Sequence diagram
