14  * A wrapper to assist in getting and setting DB information from
15  * a persistent store.
16  *
17  * This is written in the style of enhanced nodes - no state is
18  * stored in the DBStoreDesc, instead all state is in the
19  * underlying graph and this is just provided as a convenience.
20  *
21  * (We don't use enhanced nodes because, since we control everything
22  * in the persistent store system description, we can avoid any
23  * need to handle polymorhphism).
