Packt has asked me to review this book, I have just downloaded it and I will start reading it tomorrow. However one of friends told me that the book is good and it covers SOA too.
It worth to mention that BPM is an important part of Middleware which facilitates building of business processes by business users, and those processes are SOA based. I didn't use it yet, after reviewing the book I will come with an example of how to use BPM and UCM together.
I wish Packt will change their books' titles to "Hands On" :D which became very helpful to start with Oracle Middleware solutions in short time.
