Overpriced PoS
Marketing and sales bullshit straight from the SAP presentations seasoned with illogical filler text and involuntary humor (did they use machine translation?)
According to the book's editor, this is the Dream Team of Fiori/SAPUI5. I hope she's wrong.
Some quotes from the first chapters, before I gave up:
"The projection of the ABAP RESTful application programming model business object consists of a data model projection."
"App development brings many challenges. One of them is that apps have an identical visual appearance, and the handwriting of the developer can’t be recognized. Additionally, apps should behave the same way in certain situations."
