Object-oriented programming
Computer programming that defines not only the data type of a data structure but also the types of operations/functions that can be applied to the data structure. Thus, the data structure becomes an object that includes both data and functions. Programmers can create relationships between one object and another. For example, objects can inherit characteristics from other objects.
