When you look at how far hardware has come in 1/2 a century, there are some aspects of software that have made great strides, but database software applications look oh-so-similar to what they were in the 70's (post-punch cards). 3D graphics effects and combo boxes look like some of the biggest advances since "interactive screens". Network progress (including web and client/server) has contributed to this lack of significant non-network-focused progress on the side of business application software (as we work just to keep up).

But is there a chance that this slow progress could, in part, be attributed to that "relational theory" stuff that folks thought would yield advances? There have been a few, but very few, advances in "data processing". One thing relational databases did was stop the progress of much of the other database software that was out there at the time and divert the attention to everything SQL. If we focus on making SQL bigger, better, faster etc for the next several decades, I suspect we will continue at the same pace. And, yes, I read the "grid computing" and SOA sutff too.

Heavy sigh (not designating resignation). --dawn Received on Wed Apr 28 2004 - 20:45:34 CDT
