hope i explain this well. i have a similar setup, as below, but for the
"MachineCounter" table i have a finacial period. this period is essentially
a month, but items can come be in/out in the period before or after but it
still needs to be tracked in that period, so today i, may 5, i might recieve
something for the period of April. how do i do this? also i am truly
tracking three types of in/out, would it be better to have each item to track
be a seperate table and when it is tracked the system auto adds the Period
for each record in the seperate table(s)?
the one main issue i am having with the seperate table is to be able to edit
the tracking table but still have the avialability to track any period at
once.

Dear,
Can anyone help me to make good database structure?
What i have are some locations where I have some machines. Every machines
have 2 counters (IN and OUT). I need to be able to enter state of that
counters and after that to compare that values with previous entry IN and OUT
counters.
How I see it seams that somewere I need to keep information wich machine is
on wich location. Beside that I need to track information about date and time
of entries.
Situation:
Location 1 - machine1, machine2, machine3
Location 2 - machine4
Location 3 - machine5, machine6, machine7, machine8
....
I need 3 kind of reports:
○ Deference between new IN / OUT and some old IN/OUT counters for every
machine
○ Total IN/OUT for some location
○ Total IN/OUT for all location
How I need to organize this datas?
Thanks for helping me,
akioki
It seems to me you need thre tables.
Location
- LocationID
- LocationName
..
..
..
Machine
- MachineID
- LocationID
..
..
..
MachineCounter
- MachineID
- Date (date/time?)
- IN
- OUT
