RE: System Configuration

["Joe Pluta" <joepluta@xxxxxxxxxxxxxxxxx>]

C++ and SQL access to DB2/400 data is a very poor approach, except possibly
from a "platform independence" standpoint.  If you plan to move your
database to servers other than the AS/400, the design is okay, but otherwise
it's adding a lot of overhead for no reason.  Instead, they could use any
standard messaging interface, from MQSeries (for a fee) to dataqueues (for
free) to communicate with programs written in native RPG on the AS/400.
Your performance is much better, and your in-house staff can maintain your
programs without a painful and expensive learning curve.

Let the new guys write the UI, but leave the business logic in the hands of
the people who know it best - YOUR programmers.

Joe
