UML Views of the World

• UML Views of the World

1. Use Case Model
2. Static Models
3. Interaction Models

• Use Case Model

1. use case diagram
2. use cases

• Use Case Diagram

initial system model
provides a graphical representation of services the system will provide
inception phase

actor:person,system etc
use case:a function of value for the actor
communication:link between actor and use case

• Use Cases

represent function as experienced by the actor
eloboration phase

• Static Models: show the structure of the system

1. Class
2. Object
3. Package
4. Component
5. Deployment

• Class Diagram

shows relationship between classes
elaboration phase

• Object Diagram

used to give an example of how a system will look like under specific circumstances

• Package Diagram

depicts the dependencies between the packages that make up a model.

• Component Diagram

depicts how components are wired together to form larger components and or software systems.

• Deployment Diagram

models the physical deployment of artifacts on nodes.

• Interaction Models :shows the interaction of the system

1. Sequence
2. Communication
3. Activity
4. State Machine

• Sequence Diagram

kind of interaction diagram that shows how processes operate with one another and in what order
represents sequence of events
show messages passing between objects

• Communication(Collaboration) diagram

relationships between classes

• Activity Diagram

flowchart with object notation
represents task activity

• State Machine Diagram

shows how activities change the state of an object
