UML (Unified Modeling Language) cookbook to build system development artifacts (use case, component diagram, activity diagram, case diagram, object diagram, mock-up building etc). Refer to the tittle of the book, you can finish it on 24 hours without eat, pray, sleep, pee or poop. I need 1 month to finish this book, trying to get practical knowledge (artifact building block) by applying it in visual paradigm software.
