When developing an ERP-like software or any other complex business system, what resources do you go to for best practices? I'm a developer, not an accountant, not a purchaser, not a manager.

I have been tasked to come up with a list of the Business rules in one of our current applications. We have a very old document that has somethings, but has not been maintained, and as such is very outdated and inaccurate.

How do you keep track of the business rules in your application code? Lets say we are designing an order entry system. One of the business rules might be: If the stock level of an item drops below its reorder point, create a purchase order for that item to bring its stock level back up to the minimum.

Hello I'm trying to create what I think should be a relatively simple business rule to operate over repeating elements in an XML schema. Consider the following XML snippet (this is simplified with namespaces removed, for readability): <Root> <AllAccounts> <Account id="1" currentPayment="10.00" arrearsAmount="25.00"> <AllCu...
