Differerence between hibernate types: boolean, yes_no, true_false
database, hibernate, java, types
Solution
from Hibernate: http://docs.jboss.org/hibernate/stable/core.old/reference/en/html_single/#mapping-types-basictypes
boolean, yes_no and true_false are all alternative encodings for a Java boolean or java.lang.Boolean.
Problem
When to use each? To what do they map in the database?
