[mso] Re: Database Integrity

Hi Carol,

   I hope we can assume this is an MS Access database?

What Version of Access are you using? And how far along are you in the =
data that has been entered? In other words, is the database still in its =
design mode or do you already have data in the tables?

This is tuffy, but in order to help you better, I've got to know what =
you've done so far.

The only way I know of to get around the problem is to create a table =
that might look something like this:

VehicleID (autonumber)
SchoolVehicleID (indexed - Duplicates ok)
Make
Model
Actual Serial Number
Color
(and everything else the car CAN ONLY HAVE ONE OF)

For example, a car can only be one Make. It CANNOT be a Chevy and a =
Dodge at the same time. It can only have 1 VIN, and it can only be one =
model.


This table will be at the top level. Every time the school buys a new =
car, you would add it to this table.

From here on, every time you add a vehicle it will have a new VehicleID, =
but you can assign the same SchoolVehicleID.

Cheezz,,, I could lay out these tables for you in 2 minutes, but it =
would take me an hour's worth of typing to explain it.

If you email me at my address below, I'll return a sample layout. Just =
let me know what version of Access you are using, and if you already =
have data in the tables. If you already have data, then the procedure =
might be a little tricky. If you're just starting to build the =
foundation, then it's a piece a cake.

I am by no means an Access wizard, but stuff like this I can handle with =
ease.

Hello,

I have a question concerning Database Integrity.  I hope this is an
applicable topic.  If not please advise.

I am creating a database of Vehicles/Activities/MilesDriven/FuelUsed for =
our
local school system.  I need to be able to track which vehicle goes on =
what
activity and track the amount of miles being racked up on the vehicles.

Now that is not a big deal BUT when the school purchases a NEW vehicle =
they
replace an old vehicle giving it the same number.  How can I protect the
data integrity (i.e., relationship between =
vehicles/milesdriven/activity)
but use the SAME NUMBER to identify a different vehicle?

I am not very proficient with databases so am taking this very slowly as =
to
hopefully not muck it up to much.

Thanks very much for any advice/responses you may offer.

Best regards,

Carol Parent

I finally got it all together...
I just wish I could remember where I set it down.

Hello Fellow Office Dweebs,

This is my first post. (Hi Linda, Hi Dian).

I am proficient with MS Access. I don't write code, but I can do
just about everything else. Perhaps I can answer some of the basic
MS Access questions / problems.

More Later.
