Query: FANTASTICALLY CLEAR PRESENTATION OF ORACLE SERVER

As an NT Consultant with advanced LAN/WAN knowledge and some SQL background , I needed a book that would get me up to speed with Oracle FAST. Marina's book was so easy to follow that I was able to complete it in only a few days. I gained not only a good understanding of hard to understand concepts in Oracle, but also, found its numerous SQL code examples mostly (hence a 9) practical. I feel so much more comfortable with a new contract requiring me to manage 400 new Oracle Installations on NT. I plan to use this book as a constant review before tackling other more advanced books dedicated to specific areas, covered in Marina's book.
