"Oracle Application Express 3.2 - The Essentials and More" - Why this book was necessary?

 

APEX requires certain knowledge and skills before being able to use it and there is no much documentation.

Some Oracle DB components that are not used by many people such as the PL_SQL proxy must be known. Another reason is that despite APEX is a RAD tool which runs inside an Oracle database allowing you to develop applications just using a web browser, many previous skills are required, including:

  • Strong knowledge in Oracle Database administration
  • HTML, CSS and JavaScript
  • Programming
  • Networking and security

If you don't have all these skills, don't worry. This book put these required skills and knowledge all together and is a great guide to build web applications using APEX, providing you many help on all these topics. Also, the book contains a lot of examples.

Once you have all these knowledge, APEX is not difficult to use (much easier if looking at this book) and you can create the web applications really very fast.

It's impressive that you may not need to install an application server on your machine, just an Oracle Database, to make your web pages work and interact with the database, as Oracle XML DB HTTP Server with the embedded PL/SQL gateway installs with Oracle Database 11g. It provides the database with a web server and the necessary infrastructure to create dynamic applications. You have the option to use Oracle HTTP server as well (as a matter of fact, it looks like most customer s use this choice).

Important topics for building web applications like page processing, regions, session management, security, validations, and (of course) lots of web components are deeply reviewed. Even the web services support of APEX is mentioned in the book.

 

Note that APEX 4.0 was released just a few weeks ago. For further information and download, please go to http://apex.oracle.com
