> DUCC currently used flat files of serialized Java objects to store history comprising
Jobs, Reservations and Services.  And the WebServer currently caches only the most recent
4096 of each.
> Proposed is to explore the possibility of employing a DB, initially with Apache Derby,
to better manage and utilize these potentially large historical data sets.  The DB would be
owned by a new DUCC DB daemon and others such as Orchestrater, WebServer and Services Manager
would interact with it to store, update and retrieve data.
