 *
 * $Log: StDbNode.cc,v $
 * Revision 1.10  2004/01/15 00:02:25  fisyak
 * Replace ostringstream => StString, add option for alpha
 *
 * Revision 1.9  2003/12/16 01:30:32  porter
 * additional fixes for change from ostrstream to StString that were not exposed until
 * running in online
 *
 * Revision 1.8  2003/09/16 22:44:17  porter
 * got rid of all ostrstream objects; replaced with StString+string.
 * modified rules.make and added file stdb_streams.h for standalone compilation
 *
 * Revision 1.7  2003/09/02 17:57:49  perev
 * gcc 3.2 updates + WarnOff
 *
 * Revision 1.6  2001/02/09 23:06:25  porter
 * replaced ostrstream into a buffer with ostrstream creating the
 * buffer. The former somehow clashed on Solaris with CC5 iostream (current .dev)
 *
 * Revision 1.5  2001/01/22 18:37:57  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)
 *
 * Revision 1.4  2000/04/25 18:26:03  porter
 * added flavor & production time as settable query fields in
 * table &/or node. Associated SQL updated in mysqlAccessor.
 * Flavor key supports "+" as an OR symbol.
 *
 * Revision 1.3  2000/01/19 20:20:06  porter
 * - finished transaction model needed by online
 * - fixed CC5 compile problem in StDbNodeInfo.cc
 * - replace TableIter class by StDbTableIter to prevent name problems
 *
 * Revision 1.2  2000/01/14 14:50:52  porter
 * expanded use of verbose mode & fixed inconsistency in
 * StDbNodeInfo::getElementID
 *
 * Revision 1.1  2000/01/10 20:37:54  porter
 * expanded functionality based on planned additions or feedback from Online work.
 * update includes:
 *      1. basis for real transaction model with roll-back
 *      2. limited SQL access via the manager for run-log & tagDb
 *      3. balance obtained between enumerated & string access to databases
 *      4. 3-levels of diagnostic output: Quiet, Normal, Verbose
 *      5. restructured Node model for better XML support
 *
