Query: not a practical guide to Apex/HTMLDB

You might as well print the manuals that Oracle supplies with Apex/HTMLDB.This book gives no practical examples. This book does not give information about how to use features of Apex/HTMLDB in real life. It is only a list of all the features and options without explanation.After using the book for some time, I doubt the authors ever used Apex / HTMLDB in a serious way.
