Documents to learn about P6 Analytics

Hi all,

I'm trying to learn about P6 Analytics 3.1(environment has already been installed.), but I could not find the documents like the reference manual to understand the following.

     <My concern>

           - What is P6 Analytics

           - What kind of benefit P6 Analytics give users

           - Integration between P6 Analytics and other P6 products

Although I found "P6 Analytics User's Guide 1.1" on the following URL, I'm not sure whether it includes "P6 Analytics 3.1".

URL : http://docs.oracle.com/cd/E17266_01/English/Analytics/P6AnalyticsUserGuide.pdf

Could someone please give me an advice how I can get those kinds of documents??
