Study Notes

Object Orientation

  • Object orientation is a programming paradigm that models software systems as collections of interacting objects.
  • Key principles include encapsulation, inheritance, and polymorphism.
  • Objects encapsulate data and behavior into a single unit, promoting modularity and reusability.

OO Development

  • Object-Oriented (OO) development is an approach to software development based on object-oriented principles.
  • It emphasizes modular design, reusability, and extensibility.
  • The development process typically involves analysis, design, implementation, testing, and maintenance stages, with a focus on objects and classes.

OO Themes

  • OO themes include encapsulation, inheritance, polymorphism, abstraction, and modularity.
  • These themes guide the design and implementation of object-oriented systems, promoting code organization and scalability.

Modeling

  • Modeling is the process of representing real-world entities and their relationships in a structured manner.
  • It serves as a design technique for conceptualizing and communicating system architecture, behavior, and functionality.

Class Modeling

  • Class modeling involves identifying classes, their attributes, methods, and relationships to represent the structure of a system.
  • It forms the foundation of object-oriented design, facilitating code organization and reuse.

Abstraction

  • Abstraction involves simplifying complex systems by focusing on essential characteristics while hiding unnecessary details.
  • It enables developers to manage system complexity and promote clarity in design.

The Three Models

  • The three models refer to structural, behavioral, and functional models used in software engineering.
  • Structural models depict the static structure of a system, behavioral models describe dynamic behavior, and functional models outline system functions and services.

Object and Class Concepts

  • Objects are instances of classes in object-oriented systems, encapsulating data and behavior.
  • Classes define the properties and behaviors shared by a group of objects, forming the blueprint for object creation.
  • Links and associations represent relationships between objects in a system.
  • Associations define how objects from different classes are connected or interact with each other, while links represent instances of these connections.

Generalization & Inheritance

  • Generalization involves extracting common properties and behaviors from multiple classes to create more general superclass.
  • Inheritance enables the creation of new classes based on existing ones, promoting code reuse and hierarchy.
  • Navigation of class models refers to the process of exploring and understanding the relationships between classes in a system.
