Object-oriented (Object Oriented) is a software development method.
Object-oriented concepts and applications have transcended programming and software development, extending to database systems, interactive interfaces, application structures, application platforms, and distribution. systems, network management structures, CAD technology, artificial intelligence and other fields. Object-oriented is a method of understanding and abstracting the real world. It is the product of the development of computer programming technology to a certain stage.

Object-oriented is relative to process-oriented. The object-oriented method organizes related data and methods into a whole and looks at them from a more detailed perspective. Modeling the system at a high level is closer to the natural operating mode of things.
Early computer programming was based on a process-oriented approach, such as implementing the arithmetic operation 1 1 2 = 4. The problem at the time could be solved by designing an algorithm.
Object-oriented came into being when there were many problems with structured design methods.
The basic strategy of structured design method to solve problems is to examine the problem domain from a functional perspective. It regards the application as a functional module that implements certain specific tasks, in which the sub-process is the underlying functional module that implements a specific operation. In each functional module, the data structure is used to describe the organization form of the data to be processed, and the algorithm is used to describe the specific operation process.
With the continuous improvement of computer technology, computers are used to solve more and more complex problems. Everything is an object. Through the object-oriented approach, things in the real world are abstracted into objects, and relationships in the real world are abstracted into classes and inheritance, helping people achieve abstraction and digital modeling of the real world.
Through object-oriented methods, it is more conducive to analyze, design and program complex systems in a human-understandable way. At the same time, object-oriented can effectively improve the efficiency of programming. Through encapsulation technology, the message mechanism can quickly develop a new system like building blocks.
Object-oriented refers to a programming paradigm and a method of program development. Object refers to a collection of classes. It takes objects as the basic unit of programs and encapsulates programs and data to improve software reusability, flexibility and scalability.
Object-oriented thinking has been involved in all aspects of software development. For example, object-oriented analysis (OOA, Object Oriented Analysis), object-oriented design (OOD, Object Oriented Design), and what we often call object-oriented programming (OOP, Object Oriented Programming).
