Part of my database will be tracking equipment orders in my office. There are two types of orders that the user might enter: accountable or unaccountable. Both types of orders need certain common fields entered, but each order has a handful of unique fields as well.

In addition, for accountable orders, we need to keep track of each individual item, as we will need to assign each item a unique ID when it is received. For unaccountable orders, we don't need to keep track of each item, but we do need to store information about each line item. So I probably need a linked table for accountable items and another linked table for unaccountable line items.

My question is this: Should I put all orders in one table, and only fill in the fields needed for that type of order, and then make two 1-to-many relations to the two tables I would need? Or should I make two separate order tables, each with its own linked table, and then re-combine the two tables using queries (for reports and such)?

I could probably do it either way, but in your experience, which would be better and easier to manage?

Depending on the amount of data that you expect the db to hold, I would go with a master-order and a suborder-table that would hold both the accountable and unaccountable items. I simple check box (yes/no) field could identify the different types of orders. Multiple table queries across any network are extremely slow unless you have unlimited bandwidth.
