One of the products we have developed for use in teaching and as a reference is our handy Datamorphosis Data Card.  We started developing this many years ago to provide a quick reference for the basic modeling notations used in different modeling approaches. As time went on we added illustrations for modeling patterns and some of the various heuristics we have developed over the years.

The card is normally printed on both sides of 8 1/2 by 11 inch card stock and folded into three sections. The front side (pages 1-3) deals with various kinds of basic modeling configurations. The back side (pages 3-6) includes a number of modeling patterns and heuristics.
