What is the difference between OOP and OOD?
Object-oriented design (OOD) is the process of using an object-oriented methodology to design a computing system or application. This technique enables the implementation of a software solution based on the concepts of objects. OOD serves as part of the object-oriented programming (OOP) process or lifecycle.
Object-oriented methodology relies on three characteristics that define object-oriented languages: encapsulation, polymorphism, and inheritance. These three terms are elaborated below.
What are the key concepts of object-oriented design?
Object-oriented programming has four basic concepts: encapsulation, abstraction, inheritance and polymorphism. Even if these concepts seem incredibly complex, understanding the general framework of how they work will help you understand the basics of a computer program.
What is it called where child object gets killed?
Explanation: Composition occurs when child object gets killed if parent object gets killed. Aggregation is also known as strong Aggregation.
What is the object interface in object oriented design?
The ‘object interface’ defines how the object can be interacted with. An object-oriented program is described by the interaction of these objects. Object-oriented design is the discipline of defining the objects and their interactions to solve a problem that was identified and documented during object-oriented analysis .
How are output artifacts used in object oriented design?
Realize that an output artifact does not need to be completely developed to serve as input of object-oriented design; analysis and design may occur in parallel, and in practice the results of one activity can feed the other in a short feedback cycle through an iterative process.
What is the factory method in design pattern?
The Factory method is a creational design pattern that provides an interface for creating objects without specifying their concrete classes. It defines a method that we can use to create an object instead of using its constructor.
Which is an introduction to object oriented analysis?
An introduction to object-oriented analysis and design. System modeling. Conceptual model. Structural, Interaction, and Behavioral models. Design principles and Design patterns. Object-orientation is what’s referred to as a programming paradigm.
