I've heard so many wonderful anecdotes like this that perhaps the best emperical data related to implementations of various data models that we could get would be to collect such anecdotes from all angles. I'm sure there are MUMPS (e.g. Cache') anecdotes too. I have even heard a few -- not many, but a few -- relational database anecdotes. I would like to hear more -- particularly stories when a business converted from something other than IMS, IDMS, or another RDBMS to an RDBMS and ended up with a big win on their hands. I'm sure that wouldn't be a cdt thing to write up, but it could be used as one part of some actual emperical data related to various data models, maybe, perhaps?

Anyway, good story, Wol. --dawn Received on Fri Apr 23 2004 - 22:32:15 CDT
