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.
Link and Association Concepts
- 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
- Navigation of class models refers to the process of exploring and understanding the relationships between classes in a system.
