I don't necessarily agree with that. Some of the worst atrocities I have seen come from naive designers thinking normalization involves sticking every piece of text imaginable into some sort of lookup table.
Then again, I would like to see a lot more managed data handled by a dbms. The key to that is extending the system to everywhere one needs to manage data.

When you say "in the direction of OO languages", what specific features of OO languages do you desire? Received on Tue Mar 13 2007 - 17:12:59 CET
