Things become complex when we move away from reality and create a virtual geek... A music manager has photocopies on paper; he makes notes or modifies a score for one band, but keeps the score for band No. 2 as it was originally. He organizes them into binders, and these binders are watertight. A simple, software-driven, and human-friendly application will always be more efficient than a sophisticated one. Two libraries must be watertight.
