Re: Database design question

some browsers put a limitation of 32k to 64k, i think.

Rob,

My brain is stuck in DDS and subfiles. I'm not at all sure what the limit

is

for HTML.

Francis,

Exactly what is the limitation to how much data can be in a TEXT field

on

a html form? Just curious as to how big a field could be until it

fills

up the browser screen.

Re: Database design question






Or you can create a file that has a key by user, date, time, and a
sequence
number. The text field itself would be 75 or so bytes (which will fit

onto

the entry screen as a subfile). If you have merely a 3-byte sequence
number,
you can fit 74,925 bytes of notes for each user/timestamp (enough for a
fair-sized short story). Plus, it conserved disk space over large fixed
length.

Maybe, as Rob said, make them varying in length (big enough to fill

most

of
a screen), and have the sequence number; that way, if one screen isn't
enough, you can have it all under the same user and timestamp.

Tim,

A lot depends on what's going to read and write the data. On the
surface, this sounds like a good use for a CLOB (or large variable
length fields) to store the notes but if RPG/400 programs are going

to

use the data, you can't use them (CLOBs) and large fixed length

fields

would be better.

Subject: Database design question

Hello all,



I have to design a database that will hold notes keyed by a user.

These

notes can be anywhere from a few words to a several hundred. Notes

will

be
tracked by user/date/time. There can be hundreds of separate notes
entered
each day, so this database will get rather large.



As far as defining the actual field that will hold the note. I would
like
some design feedback. Should it be fixed, variable, other.



Thanks for all the input in advance.
