Conceptual Class Category

Conceptual Class Category List—SYS466
A conceptual class is a real-world concept or thing; a conceptual or essential perspective.
At the noun filtering stage we are looking for conceptual classes. As we move through
the design process we will start to design software classes that represent an
implementation perspective of a software component but we will not get into language
specific classees in 466. A conceptual class is not an implementation class, such as a class
that can be implemented in an OO language such as Java or C++. That comes much later.
