The Products resulting from the association of the operations and content can be grouped into six categories.
Units are basic elements or ideas. In the terminology of grammar, a unit functions in the same manner as a noun.
Classes refer to groups of units with common elements.
Relations are a connecting link between two units or classes. This link has its own character and is similar to the preposition in grammar. Examples are "married to" and "harder than."
Systems are complexes or organizations of interdependent, interacting parts. Examples include an outline or a mathematical equation.
Transformations occur when one item of information becomes something else. Participles describe this kind of product: shrinking or inverting.
Implications are perceptions that can be predicted, expected, or anticipated from information.
