Resource Update: GoF Design Patterns - Only notations, no text!

Sometimes, a picture is indeed worth a thousand words. Especially I always felt that the Design Patterns book was quite verbose and distracting in its approach. It would have been great if the examples had been a little more simplified and did not clutter the space. Also, a bit of comparative study of these patterns could allow one to appreciate the subtle nuances and the differences between these patterns, which look quite alike to a newbie.

Finally, I struck gold when I found this link. Some old site that contains the pictorial or PepperSeed images showcasing the Design Patterns. The notations are quite similar to UML notations. And There is astoundingly no text, whatsoever!

I find this a very essential 5 minute referesher that the Architects should keep handy for reference, whenever a moment of uncertainty, while designing a complex application, renders them actionless.

This is the link to the site. Gang of Four Design Patterns

Here is a sample of Adapter Pattern and Bridge Pattern, when placed side by side once can see the subtle difference so clearly, and without any textual clutter around it.

Bridge Pattern













I hope you appreciate the essence of text less GoF Design Patterns!
