I don't know how data is in your head.
I mean like in a hexadecimal dump of a computer memory.

Aren't the constraints the ones that define the structure of data ?

You aren't SUPPOSED to say anything.

I also meant data as the data in the computer. But you said it has no structure in the computer and the structure is in our head.
I have not said that computers cannot interpret the data. You said something like "Each head has its own opinion". I only asked where do you think is the place for integrity contraints [checking].
Sorry if it sounded philosophical.
