It would appear you are studying toward an advanced degree of some sort, which would indicate, to me, anyway, that you have mastered the art and science of research. That you ask such questions, which are not 'theoretical', but practical in nature indicates otherwise. It also indicates a laziness which may put a premature end to your career as an Oracle DBA or other Oracle database professional. Such information can be found in most of the FAQ lists published on the web and at Google, as well as the archives for this newsgroup, which you have obviously failed to search. You've been pointed to the correct source of information by another post; let me direct you further to the website where the Concepts Guide resides:

tahiti.oracle.com

I STRONGLY suggest you visit and read. You will find your answers there. I would also STRONGLY suggest you dramatically improve your research skills. The state at which they now exist is deplorable.
