//_HADES_CLASS_DESCRIPTION 
///////////////////////////////////////////////////////////////////////////////
// HParOraIo
//
// Interface class to database Oracle
// It is derived from interface base class HParIo.
//
// It contains a pointer to the connection class (type HOraConn)  and a list
// of interface classes for the detectors. Each detector has its own interface
// class all inherited from a common base class.
//
// This class replaces the former class HOraIo.
