Personally I'd like to see Oracle break all implicit conversions. Problem is that there is so much badly written code out there that they can't.

I've worked with a quite a few ... "database-unaware" apps. And have found two things.

1. Some companies figure out that they have created garbage and rewrite it. I can think of two just in Bellevue Washington alone.
2. Some managers prefer to buy projectorware. Don't test. Don't verify. And deserve the garbage they get. Caveat emptor.

Lets hope more IT people show some backbone and stop letting ignorant managers make purchases that put them into a form of virtual slavery.

I am teaching a class at the U during the Spring quarter for managers of technology projects that are not experts in technology. One might consider this Dilbert's revenge. I'm going to have 30 hours during which I am going to get to let the pointy-haired bosses see them as we see them. It should be a blast.

If you want to sign up your management have them contact me. ;-)
