Not much added to my "Quick introduction to reverse engineering for beginners" book, but couple things: how C++ objects are usually represented in low-level x86 code and also several examples related to Oracle RDBMS: how to find all information about V$TIMER view and X$KSMLRU tables, which functions are behind them, etc (section 7.3).
I also wrote small utility to extract information related to V$ views and X$ tables, it's here. But more about is in my "book".
English language version, Russian language version.
