# New and hopefully last version of the MARC-DB. Is the fastest in benchmark, everybody agree ;-) (Sergey, Steve and me, Paul)
#
# Revision 1.13 2002/06/04 Paul
# should be the last version... remains only 2 tables : the main table and the subfield one.
# benchmark shows this structure is the fastest. I had to add indicator in the subfield table. should be in a tag_table, but as it's the
# only real information that should be in this table, it has been thrown to subfield table (not a normal form, but an optimized one...)
#
# Revision 1.12 2002/05/31 20:03:17 tonnesen
# removed another _sergey
