Why is it called 'business logic'? Where did this term come from? [closed]

Answer 1

I think many times its sarcastic, because business logic is not always logical. its done certain way only, because business wants it that way - many times its not the best way. you can fight with them and (if youre lucky) make them see the light or just accept the fact that its business logic and be ready to change it when they realize they made mistake.

Answer 2

The origin of the term is in business software, where business specific rules were separated in their own modules. That merely got transferred to all the other software.

Answer 3

For the same reason that the end of a gun which the bullets come out of is called the “business end”. It's where the primary action happens.

Answer 4

Not sure, but I think the term should be replaced with domain logic instead.

Answer 5

It is a term used mainly for Line of business applications & one more way people know of it is CRUD app (create, read, update, delete).

I think it means the class(es) contain the logic of how the business process works for given business process(es).

Answer 6

Thinking about early computer systems, like credit card processing, there are two large parts to the code, the parts doing the io, talking to the back-ends, tape, etc, and the parts doing the logic of the business, rules like, is the card valid, has the limit been exceeded.

Another way to think about it, it's the things a business person would say are the 'rules' to capture.
