Query: quite useful

i am just in the middle way of reading this book, but what i have got till now is great. I have 8 years career with software development specially in java, i reached to a point am doing system architecture most of the time, but i can say i was doing it from the point of view of "House Architect", now i can see things from Tower Building Architect, or City Architect in the extreme.I did not pass the certificate yet so i dont know how much it is useful on this matter.
