### Hibernate

* Hibernate works with most current RDBMS. See  [supported databases](http://www.hibernate.org/80.html) 

* [On CascadeType.DELETE and CascadeType=DELETE_ORPHAN](http://www.mkyong.com/hibernate/hibernate-cascade-example-save-update-delete-and-delete-orphan/)

### Spring 2.0 Framework

We use the Spring 2.0 framework to develop the library and keep the coupling of components low.
