Object-oriented system development
A system development methodology that is organised around "objects" rather than "actions," and "data" rather than "logic." Object-oriented analysis is an assessment of a physical system to determine which objects in the real world need to be represented as objects in a software system. Any object-oriented design is software design that is centered around designing the objects that will make up a program. Any object-oriented program is one that is composed of objects or software parts.
