Database (urd) Design Strategy

[armsys]

What would be the most optimal strategy to Database Design as far as UR is concerned?
My understanding at Kinook all data are centralized and consolidated in a single urd. My concern about such strategy is the likelihood of attracting a great deal of noise when searching.
Just imagine mixing Info Items on R&D, tech support, marketing & sales, to-do lists, travel plan, lecture notes, readings,...etc.
Or should we separate all above-mentioned Info Items into separate urds.
