At a database conference in 1998, I heard that IBM was actually experiencing an increase in the number of IMS licensees. Companies were bringing in consultants and veteran developers for Y2K. Perhaps they were also using them to work through an application development backlog on some legacy hardware.
IMS may prove to be as venerable as the C-47 (DC3) aircraft. Received on Mon May 03 2004 - 08:04:29 CEST
