Module Overview

This module introduces the transition to object-oriented analysis and design, focusing on Use Case Modeling and Class Diagrams as central tools in software development.

Learning Objectives

This section outlines the learning objectives for a module on Object-Oriented Analysis and Design with an emphasis on UML diagrams, including Use Case Modeling and Class Diagrams.

Lecture 31: Use Case Modelling - Capturing Functional Requirements From A User's Perspective

This section introduces Use Case Modelling as a technique for capturing functional requirements from the user's perspective, facilitating better communication among stakeholders.

Introduction To Use Case Modelling

Use Case Modelling captures functional requirements from a user's perspective, highlighting system-user interactions.

Key Elements Of A Use Case Model

This section outlines the key elements of a Use Case Model, emphasizing the roles of actors, use cases, system boundaries, and their relationships in capturing functional requirements from a user's perspective.

Use Case Diagram

This section introduces Use Case Diagrams as a tool for capturing functional requirements and facilitating communication between users and developers.

Use Case Specification (Use Case Description)

This section discusses the essential components of a Use Case Specification, which documents the functional requirements of a system as seen from the user's perspective.

Lecture 32: Factoring Use Cases - Managing Complexity With Relationships

This section introduces 'Factoring Use Cases' by discussing the concepts of include and extend relationships to enhance clarity, promote reusability, and manage complexity in Use Case Models.

The Need For Factoring Use Cases

Factoring Use Cases helps in managing complexity and promotes reusability in Use Case Models through specific relationships.

Relationships Between Use Cases

This section explains the relationships between use cases, specifically focusing on <<include>> and <<extend>> relationships that help manage complexity in use case modeling.

Generalization (Inheritance) Relationship For Actors (Optional But Useful For Nptel)

When To Use <<Include>> Vs. <<Extend>>

This section distinguishes between the <<include>> and <<extend>> relationships in Use Case Modeling, focusing on their purposes and appropriate usage.

Best Practices For Factoring Use Cases

This section offers best practices for factoring use cases in order to manage complexity and enhance reusability within Use Case Models.

Lecture 33: Overview Of Class Diagrams - The Static Structure Of Objects

This section provides an overview of Class Diagrams in UML, focusing on the static structure of object-oriented systems.

Introduction To Uml (Unified Modeling Language)

This section introduces UML as a standard modeling language in software development, focusing on Use Case Modeling and Class Diagrams for capturing system requirements.

Introduction To Class Diagrams

Class Diagrams provide a visual representation of the static structure of object-oriented systems, depicting classes, attributes, operations, and relationships.

Representing A Class In A Class Diagram

This section focuses on how to represent classes, including their attributes and operations, in Class Diagrams as a core aspect of UML.

Abstract Classes And Concrete Classes

This section explains the distinction between abstract classes and concrete classes in object-oriented programming, highlighting their roles in class structures and inheritance.

Interfaces

This section delves into the concept of interfaces in object-oriented programming, elucidating their role in defining contracts and enabling polymorphism.

Lecture 34: Inheritance Relationship - Generalization And Specialization

This lecture examines the concept of inheritance in object-oriented programming, focusing on the generalization and specialization of classes.

Introduction To Inheritance (Generalization/specialization)

This section introduces the concept of inheritance in object-oriented programming, highlighting the relationships between classes and the benefits of generalization and specialization.

Notation For Inheritance In Class Diagrams

This section covers the notation for inheritance in class diagrams, a fundamental aspect of class design in object-oriented programming.

Details Of Inheritance

This section explores the concept of Inheritance in object-oriented programming, highlighting its purpose, notation, and implications for design and implementation.

Implications For Design And Implementation

This section discusses the implications of inheritance and association relationships in object-oriented design, focusing on their roles in system architecture and design choices.

Lecture 35: Association Relationship - Structural Connections Between Classes

This lecture explores the Association relationship in UML, focusing on its purpose, notation, and properties like multiplicity, role names, navigability, and the specialized forms of aggregation and composition.

Introduction To Association Relationship

The Association relationship in UML is essential for depicting how classes connect and interact, encompassing concepts such as multiplicity, role names, and navigability.

Notation For Association In Class Diagrams

This section delves into the Association relationship in Class Diagrams, illustrating its purpose, notation, and various properties essential for object-oriented design.

Types Of Associations - Specialization For Whole-Part Relationships

This section discusses the types of associations in UML, focusing on the structural relationships between classes, including simple associations, aggregation, and composition.

Reflexive Association

Reflexive associations are connections within a class, indicating relationships among instances of that same class.

Implications For Design And Implementation

This section discusses the implications of object-oriented design principles for software design and implementation, particularly focusing on inheritance and association.
