Study Notes
Object-Oriented Analysis and Design (OOAD)
- OOAD uses models to visualize application components around objects
- Development stages include analysis, design, and implementation
- Analysis involves formulating the problem, identifying user requirements, and creating models of how the system should operate
- Design includes system design and object design: system design focuses on system architecture, object design focuses on objects and their interactions
- Implementation translates the design into code in a programming language; involves database creation and testing
Development Life Cycle (SDLC)
- Effective SDLC results in high-quality systems meeting customer expectations and completing within budget and time constraints
- SDLC uses policies and procedures for system development throughout its lifecycle
- Includes activities like requirements, design, implementation, testing, deployment, operations and maintenance
- Phases within the SDLC include initiating, planning, analysis, design, implementation, testing, deployment and maintenance
Problem Statement
- Describes the problem, desired state, and gaps between the two.
- Ideal situation, current reality, consequences, and proposal (solutions) should be included.
- Important to identify the what and why of the problem.
- Includes quantifiable information like lost time, money, etc.
System Analysis
- System Analysis determines and identifies system requirements, identifying and defining classes and their relationships.
- Techniques used include object modeling, dynamic modeling, functional modeling
- Object modeling focuses on objects and classes and their attributes and relationships
- Dynamic modeling examines how objects and classes change over time and respond to events
- Functional modeling depicts operations and data flow within objects and classes
