OOABAP - Preactical Use
I recently read the book ABAP Objects by Horst Keller & Sascha Kruger. I understand the concepts of Object Orientation, but I can hardly find any practical implementation of them in my day to day ABAP programming - for example, I know what singleton class is and how to create one, but where do we use it? I don't think it'll be of any real use to us if we just know it theoretically. Is there any other book/material that explains where exactly we can implement these concepts? Or if anyone here has worked on OOABAP extensively can you please let me know? It'll be of great help.
