Questions about books, publications and groups dealing with DB2/400

["Dave Odom" <Dave.Odom@xxxxxxxxxxxx>]

Does anyone know of Paul Conte?  Does anyone have any opinions on his
publication on DB2/400?    Are there any other well written publications
about DB2/400 (not the native flat file(non-relational) structure used
by most iSeries folks)?  Any other good publications on DB2/400(again,
DB2 using DDL & DML, not flat-file(non-relational) DDS)?    

Is DB2/400 still not well embraced by IDUG?   Anyone know why?  Is that
because it and its members doesn't see DB2/400 as a real version of DB2
or because there are not enough DB2 RDBMS  applications on the AS/400
like on the other IBM platforms or is it because there is no real AS/400
community effort to convince IDUG the AS/400 is a viable DB2 platform 
or what?  
 
Thanks,

Dave Odom
