Detailed Description

The starting point for the public API of the Conditions/DB.

This is a simple implementation for a singleton interface on the top of the "old" BDB API. Here is how the concepts of the new API map onto the old one:

• Only one database is available.

• Only one view per database is available.

• Only one (except the ROOT DIR) level of folders is available. This level corresponds to the "detector" or "susbsystem" concept of the old API.

• Conditions are only available beneath the "susbsystem" level.

• The condition type corresponds to the "origin" in the old API.

• There is just one unit of measurement of the validity dimention - BdbTime.
