Object-oriented programming (OOP)
An approach to program design in which a program consists of a collection of objects that contain data and methods to be used with that data.
Procedural programming
An approach to program design in which a program is separated into small modules that are called by the main program or another module when needed.
Aspect-oriented programming (AOP)
An approach to program design in which different functions are clearly separated so program components can be developed and modified individually from one another, and the components can be easily reused with separate, non related objects.
