UML Activity diagrams...

• can contain decision branches

• can show parallel operations

• show the class structure of an application

• model the state of a system

UML sequence diagrams

• are dynamic diagrams showing the operation of a program

• are static diagrams showing the structure of a program

• show classes and the message flow between them

• shows relationships between classes

The flow in UML Sequence diagrams...

• always start at the top left

• end at the bottom right

• end at the bottom left

• start and end anywhere

UML Sequence diagrams...

• can model loops

• can model conditional flows

• show the state of objects

UML class diagrams...

• are dynamic diagrams showing the operation of a program

• are static diagrams showing the structure of a program

• visualize classes and their relationships

• do not show relationships between classes

Classes in UML class diagrams...

• are represented by rectangles

• show the class name

• show the classes operations / methods

• show only public class attributes

Data types in UML class diagrams...

• are not visualized

• are shown before the attribute / parameter name

• are shown after the attribute / parameter name

Software Engineering...

• describes the transformation from requirements to a working system
