The document discusses use case diagrams for systems analysis and design. It provides examples of use case diagrams for an appointment system and an ATM system. Key elements of use case diagrams are described, including actors, use cases, relationships like generalization, include and extend, and the system boundary. The ATM system example demonstrates how a use case diagram can model the interactions between an actor (user) and the various functions of an ATM machine like checking balance, transferring money, withdrawing money and logging out.

4. System Analysis and Design with UML
1. System Analysis
1. Business Process Identification
• Use Case Diagram
2. Business Process Modeling
• Activity Diagram or Business Process Modeling Notation
(BPMN)
3. Business Process Realization
• Sequence Diagram (Buat untuk setiap use case dengan menggunakan
pola Boundary-Control-Entity)
4

5. Use Case Diagrams
• Summarized into a single picture
• All of the use cases for the part of the system being modeled
• Use case represents the discrete activities performed by the
user
• Use Case Diagram tells what the system will do
• Good for communicating with users
5

6. Syntax for an Use Case Diagram
• Actor
• person or system that derives benefit from and is
external to the subject
• Use Case
• Represents a major piece of system functionality
• Association Relationship
• Include Relationship
• Extend Relationship
• Generalization Relationship
<<extends>>
<<includes>>
6

7. Use Case
• A major piece of system functionality
• Can extend other Use Cases
• Placed inside system boundary
• Labeled with descriptive verb - noun phrase
Use Case
7

8. System Boundary
• Includes the name of the system inside or on top
• Represents the scope of the system
• Actors are outside the scope of the system
Boundary
8

9. Actor
• A person or another system that interacts with the
current system
• A role, not a specific user
• Provides input, receives output, or both
actor
Actor/Role

10. Association Relationship
• Links actor and the Use Case
• Shows two-way communication
• If one-way, arrows are used
• * is for "multiplicity of the Association"
* *

11. Extends Relationship
• Extends Use Case to include Optional behavior
• Arrow points from the extension Use Case to the
base Use Case
extend
extend Make
Appointment
Make Payment
Arrangement

12. Include Relationship
• Include one Use Case from within another
• Arrow points from base Use Case to the
included Use Case
include
include Create New
Patient
Make New
Patient Appointment

13. Generalization Relationship
• A specialized Use Case to a more generalized Use
Case
• Arrow points from specialized to general Use Case
