What's considered the best way to declare db connections? Declare them global in a module, so they're available everywhere, but always in memory, or declare them in each sub & function, increasing overhead but saving memory? Or declaring them in a module, but instantiating in each sub?
It may not be a big savings either way, but I have to deal with some machines that only have 32 mb ram. And I just like cleaner, more efficient code. Thanks.
