Evolutions of architectures
This appendix details dozens of evolutions of metapatterns to show how they connect together. The evolutions probably have practical value through listing prerequisites, benefits, and drawbacks, but I am not sure that many readers will get through them without becoming bored to death. The metapattern chapters in the main parts of the book include abridged versions of the sections below.
Duplicate and similar evolutions are omitted, and I did not write any evolutions for fragmented metapatterns as you should be able to infer them on your own after having read the book. Furthermore, for some reason I don’t know of any evolutions for the implementation metapatterns, except for those that re-integrate the custom parts of the system into its core, mostly to improve the system’s performance. However, such evolutions are trivial, thus omitted.
