What is object-oriented programming (OOP)?
Object-oriented programming (OOP) is a computer programming model that organizes software design around data, or objects, rather than functions and logic. An object can be defined as a data field that has unique attributes and behavior.

OOP focuses on the objects that developers want to manipulate rather than the logic required to manipulate them. This approach to programming is well suited for software that is large, complex and actively updated or maintained. This includes programs for manufacturing and design, as well as mobile applications. For example, OOP can be used for manufacturing system simulation software.

The organization of an object-oriented program also makes the method beneficial for collaborative development, where projects are divided into groups. Additional benefits of OOP include code reusability, scalability and efficiency.

The first step in OOP is to collect all of the objects a programmer wants to manipulate and identify how they relate to each other -- an exercise known as data modeling.
