The framework supports two bean modes: BACKED and SIMPLE (com.softwareag.centrasite.appl.framework.persistence.BeanMode). This mode specifies how the beans interact with the underlying implementation of the API supporting JAXR.

When using the SIMPLE mode, data from the bean is transferred to the registry object only when the user explicitly requests this by calling one of the BeanPool methods (update(), flush(),delete()).

When using the BACKED mode, data from the bean is transferred to the registry object immediately after it is set in the bean. The advantage of this is that extra features such as locking and caching can be used.
