Questions and Answers

What are the three major phases in the object-oriented software development process?

The three major phases are object-oriented analysis, object-oriented design, and object-oriented implementation.

Describe the focus of object-oriented analysis in software development.

Object-oriented analysis focuses on formulating the problem, identifying user requirements, and building a model based on real-world objects.

What is the difference between system design and object design in the object-oriented design phase?

System design involves creating the complete architecture of the system, while object design focuses on identifying classes and their relationships based on that architecture.

What decisions are made during the object design phase regarding class creation?

During the object design phase, decisions are made whether to create new classes from scratch, use existing classes, or inherit from existing classes. Signup and view all the answers

How does the object-oriented methodology help in visualizing applications?

The object-oriented methodology visualizes applications by using models that are organized around objects, making complex systems easier to understand. Signup and view all the answers

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
