I have read the the forum that it is suggested to  separate the  Human Tasks 
Tables  and the JBPM5 tables in different databases. Together with the  
http://docs.jboss.org/jbpm/v5.3/userguide/ch.core-persistence.html#d0e3800 
documentation section 8.3 , it said :

  Storing history information in the runtime database can result in the 
database rapidly increasing in size, not to mention the fact that monitoring 
and analysis queries might influence the performance of your runtime engine. 
This is why process execution history information and runtime state should be 
stored separately.

So , I want to ask inbest practice , we should   use 3 databases for the JBPM5 
project ???

* A database  for storing runtime data which has the following tables only  : 
eventtypes , processinstanceinfo , sessioninfo , workiteminfo
* A database for storing history information  (BAM purpose) which has the 
following tables only : nodeinstancelog, processinstancelog , processinstancelog
* A database for the human task
