What is meant by object-oriented design?
What is meant by object-oriented design?
Object-oriented design is the process of planning a system of interacting objects for the purpose of solving a software problem. It is one approach to software design.
What are the 4 pillars of object-oriented design?
The four pillars for OOP are Abstraction, Encapsulation, Inheritance, Polymorphism. Abstraction : Abstraction is the process of showing only essential/necessary features of an entity/object to the outside world and hide the other irrelevant information.
What is object-oriented design explain with class diagram?
Class diagram is the backbone of object-oriented modeling – it shows how different entities (people, things, and data) relate to each other. In other words, it shows the static structures of the system. A class diagram describes the attributes and operations of a class and also the constraints imposed on the system.
What is oops and its types?
Object-oriented programming is a model that provides different types of concepts, such as inheritance, abstraction, polymorphism, etc. These concepts aim to implement real-world entities in programs. They create working methods and variables to reuse them without compromising security.
What are the advantages and disadvantages of OOP?
Comparison Table for Advantages And Disadvantages Of Oop
| Advantages | Disadvantages |
|---|---|
| We can reuse the code multiple times using class | Size is larger than other programs |
| Inherit the class to subclass for data redundancy | It required a lot of effort to create |
| It is easy to maintain and modify | It is slower than other programs |
What means in UML?
Unified Modeling language
Unified Modeling language (UML) is a standardized modeling language enabling developers to specify, visualize, construct and document artifacts of a software system. Thus, UML makes these artifacts scalable, secure and robust in execution. UML is an important aspect involved in object-oriented software development.
What are OOP principles?
The basic principles of OOP involves Abstraction, Encapsulation, Inheritance, and Polymorphism. There are also objects and classes. Together, they stand as the working principle of any object-oriented programming language.
What are the steps involved in Object-Oriented Design?
Let’s get started…..
- STEP 1: Requirement Analysis: The first step in the process is to understand the requirement of the system or feature properly.
- STEP 2: Define the Use Cases.
- STEP 3: Identify the Actors.
- STEP 4: Identify The Scenarios.
- STEP 5: Use Case Diagram.
