Isn't that a kind of half baked, guaranteed-incomplete kind of model checking?

can you explain what these integrity protections are and why they're needed, or give a link? TIA

Entirely credible. Right at the top it says it's a stealth aircraft. It's just doing what it does best.

Laws very often look for intent of actions as well as the actions themselves. And they are ambiguous: "beyond reasonable doubt" is what, as a percentage, in your view?

Skimmed it. Weird read. I'll come back for a proper read later. Intriguing. Nummulites are (were? Thought they were extinct?) single celled : "A nummulite is a large lenticular fossil, characterised by its numerous coils,[1] subdi

Let me take a tangent to this, a couple of decades ago I was using Delphi and it was marvellous. A couple of years ago I tried to do some equivalent front-end building backed by a database, in Visual Studio and it was a bloody nightmare. Co

Thanks for a polite disagreement, but I believe you are wrong (not saying you are!). IIRC Codd defined relation valued attributes and also associated operators Group and Ungroup. https://www.oreilly.com/library/view&#x2

On your first para I'm not remotely sympathetic. They are using a complex, sophisticated tool without understanding it. They got what they deserved. Particularly telling is this ridiculous quote "I'm a little disappointed tha

Out of my depth here (no experience) but "Codds relational database model adds the further constraint that nested tables are not allowed" may be wrong. He allowed nested stuff, it's just that SQL didn't support it. Can a

Excellent presentation, no dumb graphics, witticism, silly voices or stupid faces pulled etc, just nice clean explanation. Nice toy too. I'd get one but I'd turn it on 3 times then get bored and give it away.

It's 99.99999999% likely to be total tripe, but I don't like the way you shut the door on it so strongly. You should allow even a small chance of it being correct, and a larger chance of it being incorrect but perhaps interesting.

Cost. Not only in extra memory but I rather suspect, in access patterns as well. So cost in speed too.

Thank you. I guess I misread. "For example, e-mails and urls are a special syntax. Their value space..." seemed to talk about the 'value space' of strings (these being e-mails and urls), not types (of e-mails and urls),
