Object-oriented design

Object-oriented design (OOD) is a design method in which a system is modelled as a collection of cooperating objects and individual objects are treated as instances of a class within a class hierarchy .

Four stages can be identified:

1. Identify the classes and objects
2. Identify their semantics
3. Identify their relationships
4. Specify class and object interfaces and implementation

Object-oriented design is one of the stages of object-oriented programming.
