Mike, the numbers are both "data base numbers" and one half of a "project number". In order to track the kits in a PC database, they had to have numbers assigned to them, because, as you can see, just saying ERTL # 9089 wouldn't work (14 different builds would have had the same number)
I gave the decal sheets that same system, with a letter for each marking option on the sheet. I used the kit number and a letter for each scheme of the first box of each kit.
That way, to do The VA-86 Xtradecal scheme on an Airfix new tooled Scooter, I just type 9677d on a project sheet, and choose kit number 2118,,,,it is a relational database, so it can autofill the project sheet's fields for me from the decal and kit data I have inputed. One day soon, I will have the references all keyed in and can have those auto-filled too.
The project will have over 200 aircraft in it when it is finished, automating some of these planning effort saves me time, and gives me more build time. Imputing my needed items that I am short of onto Scalemates Wishlist gives me a way to pick up more of anything that I know I will need down the road,,,,,,since aftermarket items almost always are OOP the day they are released, especially decal sheets. (if you realize that they are only going to print a sheet once, whatever number they print is the total that all of us will be able to buy from, that makes them OOP on intro date)
The numbers also make it easier to get "one of each tooling of the subject in 1/72", which turned out to be a side-subject of my collection theme.
a few minutes typing each time I buy things saves me all of that walking around looking for things, or trying to remember if I have enough of this or that, etc
