// $Log: BrRunsDb.h,v $
// Revision 1.3  2002/04/16 13:24:57  hagel
// Implement support for access using BrDbConditionsKeithley
//
// Revision 1.2  2001/10/08 11:02:48  cholm
// Implemented the polymorphic access approach.
//
// Revision 1.1.1.1  2001/06/21 14:55:17  hagel
// Initial revision of brat2
//
// Revision 1.6  2001/06/18 10:31:22  cholm
// Changed the connection scheme to the databases.  No more explicit passwords,
// and better handling for diconnecting from the databases.  Password is stored
// internally, so that one may connect and disconnect with out the need to read
// password from file or user input over and over again.  Preferably, the
// password should be stored in some kind of same memory or encrypted.  However,
// for the time being I'm ok with this, since attaching a debugger is probably
// only allowed for the owning user, so no-one can peek at the memory.
//
// Revision 1.5  2001/01/19 16:30:30  cholm
// Revisited the Run database classes. Deleted old implemtation via BrRun,
// and put in BrDbRun, BrDbFile, BrDbMagnet, BrDbConditions*, and
// BrDbShiftReport. A description will be posted to brahms-dev-l soon.
//
// Revision 1.4  2000/08/15 22:24:03  hagel
// Changes to fit BRAHMS DB convention
//
// Revision 1.3  2000/08/10 22:00:17  hagel
// First version of small fixes as per Christian suggestion
//
// Revision 1.2  2000/08/09 22:27:24  hagel
// Changes to implement BrRun
//
