In a few days I will give a presentation at UKOUG Tech15 about Global Data Services, it will be the first time that I present this session.
I usually like to give the link to the material to my audience, so here we go:
Credits
I have to give special credits to my colleague Robert Bialek. I’ve got a late confirmation for this session and my slide deck was not ready at all, so I have used a big part of his original work. Most of the content included in the slides has been created by Robert, not me. (Thank you for your help! :-))
