Query: Unrewarding slog

Ok, I just don't get it. "Building the data warehouse" feels like a padded and generally under-edited collection of essays on topics of varying interest. Its focus is "orthogonal" to that of Kimball's "Data warehouse toolkit"; Chapter 13 is the easy-to-see overlap, but gave me no clue about the nature of the supposed "Team Edward vs. Team Jacob"-scale conflict between the two camps. However, as far as writing is concerned, the comparison with Kimball's book is clearly not in favor of Inmon's thicker tome, highlighting its frustrating tendencies for vagueness and hand-waving.
