I am of the opinion, and I freely admit it's my own bias, that it is
redundant to store calculated fields in data. If your feuillet page
is always NbCar / 1500 I see no reason to store it. Simply calcluate
it on the fly when you display it.
As an example, I keep gas mileage statistics for my motorcycle. All I
store are the date, mileage, miles on tank (my mileage odometer
doesn't have tenths, so I use trip odometer A for gasoline purchases),
number of gallons purchased, and the miles remaining in tank reading
from the bike's computer (I like to test its accuracy - I find this
highly entertaining). Then when I display the data I use cat and pipe
the output through awk (with a lot of other bells and whistles) and
let awk calculate my mpg and actual miles remaining in tank before it
shows it all to me.
It's a simple awk because my data is reliably static, so I can show it
here:
<awk>
{ /* print */
dt = $1
mileage = $2
miles = $3
gal = $4
rem = $5
arem = (6 - gal) * (miles / gal)
if (length(miles) > 0 && length(gal) > 0) {
if (length(rem) > 0) {
printf "%10s %8s %7s %7s %6.1f %5.0f %5d %6.1f\n", dt, mileage,
miles, gal, miles / gal, miles * 6.0 / gal, rem, arem
} else {
printf "%10s %8s %7s %7s %6.1f %5.0f\n", dt, mileage, miles, gal,
miles / gal, miles * 6.0 / gal
}
} else {
print
}
}
</awk>
with apologies for mailer wrap.
You could easily modify this to your purpose...
