Oracle ACE, Asif Momen’s first book is released from Packt Publishing: Oracle Database XE 11gR2 Jump Start Guide. As you know, Oracle Database XE is a free version of the Oracle RDBMS. Oracle XE is limited to only use one CPU on a system; use up to 1GB of RAM; store up to 11G of user data. These limitations shouldn’t make you think that Oracle Database XE is not good for production. It’s a great product for small applications and can be upgraded to other Oracle versions if needed.
In his book, Asif Momen guides you how to install and use Oracle XE and explains fundamentals of Oracle Databases and Oracle Application Express.
