> 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.
