What is the archtetype/instance pattern?

The archetype/instance pattern happens when one entity tracks occurrences of another entity. A common example is the relationship among CLASS and SECTION, where the actual occurrence of a class occurs when students register for a SECTION of that CLASS. The archetype/instance pattern is executed as an ID-dependent relationship.
