John Lam tries to define “Enterprise” software. One aspect of his definition is:
Enterprise applications are used by more than one person concurrently
This seems to be a pretty broad statement, IMO. Our two outside salespeople share a sales database. Does this mean it’s an “enterprise” application?
I think the term “enterprise” should also include a size component. Architecturally, though, I suppose the issues may be the same whether it is two users or 2000 users.
