What is the object-oriented programming system?

In an object-oriented system, all data is represented as discrete objects with which the user and other objects may interact. An object-oriented system allows the user to focus completely on tasks rather than tools. Examples of object-oriented programming languages include C++ and Smalltalk.

How does one properly identify the classes and objects that are relevant to a particular application?

Start with a scenario (usually representing a normal course through a use case) Identify initial classes/objects and make cards for them (this is can often be done by picking out the nouns) Going through a scenario helps identify responsibilities of a chosen object.

How do you identify objects and classes?

1. Find the nouns. Read through the problem statement and the associated documentation and highlight the nouns.
2. Evaluate the nouns to find classes. Questions to ask to evaluate nouns to find classes:
3. Define the purpose.
