* NAME
*	Database
*
* DESCRIPTION
*	The OpenSM database interface provide the means to restore persistent
*  data, query, modify, delete and eventually commit it back to the
*  persistent media.
*
*  The interface is defined such that it can is not "data dependent":
*  All keys and data items are texts.
*
*	The DB implementation should be thread safe, thus callers do not need to
*  provide serialization.
*
*	This object should be treated as opaque and should be
*	manipulated only through the provided functions.
