Relational Database Management Systems
Thank you very much for buying this book (or for getting a legal copy). Database administrators have access to valuable and confidential data belonging to their organizations and therefore must possess high ethical standards. (Consider this your first lesson in Oracle Database administration.) Besides, royalties paid to textbook authors typically constitute no more than minimum wage for the long hours they spend writing, so the least you can do to respect their effort is to buy their books or get legal copies.
