OOP Terminology: class, attribute, property, field, data member

Question

I am starting studying OOP and I want to learn what constitutes a class. I am a little confused at how loosely some core elements are being used and thus adding to my confus

Answer 1

I discovered in my question that Properties as defined in .Net are just a convenience syntax for code, and they are not tied to underlying variables at all (except for Auto-Implemented Properties, of course). So, saying "what is the difference between class property and class field" is like saying: what is the difference between a method and an attribute. No difference, one is code and the other is data. And, they need not have anything to do with each other.

It is really too bad that the same words, like "attribute" and "property", are re-used in different languages and ideologies to have starkly different meanings. Maybe someone needs to define an object-oriented language to talk about concepts in OOP? UML?
