Oracle Application Express 3. 2 - the Essentials and More : Develop Native Oracle database-centric web applications quickly and easily with Oracle APEX

Great book on Oracle Application Express (APEX), good way to get started and nice reference for more advanced developers. Very well structured. I think especially the first three chapters provide a great introduction into APEX, starting with defining what this product is actually all about, followed by a very good definition of the various technologies and standards used on APEX , and then providing a nice overview of the basic concepts. Subsequent chapters provide a nice reference on concepts like items, computations, validations, processes, etc. And even though APEX 4.0 was recently released, this book on APEX 3.2 is still very relevant and useful for anyone learning to develop web applications with APEX, regardless of whether APEX 3.2 or 4.0 is used.
