PI 7.1 Java Mapping Source Control

Hi Guys,

I was wondering if any of you could shed some light on source control when developing Java Mappings in PI based on your experience. Or could you please point me in the right direction with some links where I can gather more information around this topic? I basically have two questions to things I'd like to find out before I start the dev.

What the pros and cons were for using NWDI as the source control and framework to develop Java mappings in PI?

Are there any other (more efficient) options that serve the same purpose?

Thanks in advance for your help.
