I bough this HTML-DB book and the Oracle Press one and there is no real comparison. The Oracle Press book spews silliness about how HTML-DB is like .NET and other off-base text that makes it look like that don't use APEX every day.This book is clearly written by APEX developers and it has sample code to show how to implement difficult HTML-DB constructs like repeating update lists and advanced security.I really needed a good reference and this is the one to buy.
