This document discusses object-oriented software development processes and use case modeling. It covers the evolution of development processes like the waterfall model and unified process. Use case modeling identifies actors, use cases, and scenarios to define system requirements. Use cases are then used to identify real-world entities and candidates for classes with attributes and messages. The document also addresses programming problems, UML diagrams, writing code with header and CPP files, and simplifications.

Assistant Professor of Computer Science

2. Evolution of the Software Development Processes:
• The Waterfall Process
• Object-Oriented Programming
• Modern Processes – UML
• The Unified Process is divided into
four phases:
• Inception
• Elaboration
• Construction
• Transition
• Iterations.

3. Use Case Modeling:
• Actors - Initiators
• Provide information to the system
• Need information from the system
• Assist other actors
• Use Cases – Specific Task
• Scenarios
• Use Case Diagrams
• Use Case Descriptions
• From Use Cases to Classes
• real-world entities
• candidates for classes
• Attributes
• Messages
• Interaction diagram
• Sequence diagrams
System Boundary
Actor
Use Case
Associations

4. The Programming Problem:
• Hand-Written Forms
• Assumptions
• UML Diagrams
• Writing the Code
• The Header File
• Class Declarations
• Attribute Declarations
• Aggregates
• The .CPP Files
• More Simplifications
• Interacting with the Program
