 ***************************************************************************
 *
 * $Log: StDbConfigNodeImpl.hh,v $
 * Revision 1.2  2011/11/28 17:03:08  dmitry
 * dbv override support in StDbLib,StDbBroker,St_db_Maker
 *
 * Revision 1.1  2001/01/22 18:37:52  porter
 * Update of code needed in next year running. This update has little
 * effect on the interface (only 1 method has been changed in the interface).
 * Code also preserves backwards compatibility so that old versions of
 * StDbLib can read new table structures.
 *  -Important features:
 *    a. more efficient low-level table structure (see StDbSql.cc)
 *    b. more flexible indexing for new systems (see StDbElememtIndex.cc)
 *    c. environment variable override KEYS for each database
 *    d. StMessage support & clock-time logging diagnostics
 *  -Cosmetic features
 *    e. hid stl behind interfaces (see new *Impl.* files) to again allow rootcint access
 *    f. removed codes that have been obsolete for awhile (e.g. db factories)
 *       & renamed some classes for clarity (e.g. tableQuery became StDataBaseI
 *       and mysqlAccessor became StDbSql)
