Origin of row/column based database software

a name for it from forty years ago was "flat-file database". It was quite
common for simple data in the EAM ("electronic accounting machine"
(punchcard)) days. But it didn't have the "interactive" screen nature
that you want.
I remember in 1967, Wilson Price telling Ben Micallef that someday
all end user would have machines on their desks to do it on TV screens.
Micallef said, "May we live so long" (idiomatic for "no way") He did NOT
live to see it.
When VisiCalc came out, although it was "intended" for arithmetic
use, LOTS of people used it for keeping track of simple record/field
data.
And, of course, all of the VisiClones, such as Lotus and Excel ended
up being used for it. I have Excel business database files that used to
be Lotus files that used to be Visicalc files. And somewhere,...
I should still have some that used to be punchcards (manually reentered
into Visicalc).

It was traditional in Data Processing to have "data entry" completely
separate from interactive use of the data. And data entry is STILL
usually done by showing a single record at a time on the screen.

Yes, it WAS an obvious thing to do.

No, your prograam was NOT the first. In the 1960s, with punchcards for
data storage, and using a 407 to print it out as rows and columns, I
maintained a few minor databases, such as name and address files.
I don't consider the 407 to be a computer. I consider it a
board programmable free-standing peripheral. (EAM machine!)
If we call the 407 a computer, then we'd also have to call
the duplicator and the interpreter computers.

Hollerith 1890 ?

Get a patent, and hold the entire world hostage!
