I've always thought that's *exactly* what makes it a text file. If
every character's ascii value is between 32 and 126, along with
CarriageReturn and Linefeed, it's a text file, regardless of how
readable it is, because it's a whole lot more readable than stuff with
the upper 129 chars and the miscellaneous control characters (Bell,
Now being a text file doesn't guarantee reasonable readability or

with a text file, at least you've got a fighting chance to reverse
Now that we have UDF-8, my definition is no longer valid, but if you've
worked a lot with ascii, you kind of "know what I mean".

I think the requirement is that the primary key is meaningless. Whether
it's an integer or a string is an implementation detail, I believe. And
of course, people violate the requirement all the time: How many use
social security number as the primary key (what could *possibly* go

I don't remember all the OP's requirements, but there's an excellent
"database" with the unfortunate name NoSQL, available at
This database was called NoSQL long before the word "NoSQL" was a
buzzword adjective. Basically, what it does is map storage and
retrieval commands to sets of Unix directories and commands like cut,
sort, grep, awk and the like. NoSQL "tables" are trivial to read with
the naked eye, but it gives you Unix-command based readers to put
headers and column spacers and the like. It's pretty cool, and it's
surprisingly fast. So SQL isn't a requirement, this can be an excellent
