Please don't be intimidated by general pronouncements about how you "should" name things. They are your things, after all. Maybe your name "Manager" is better than "Connection Manager" because it's shorter. Especially so if that section of your code mainly manages "connections" and little else.
I believe that such books have very useful ideas, but only for coders who will never read them. Why? Because engineers who do read such books have already internalized and incorporated the soundest of the principles in them. And coders who won't read them don't care.
