Negative Positive
Title: too vague
Review: The author discusses some interesting topics, but I found the book far too full of vague statements about the usefulness of various ways of encoding XML and of database architecture. Similarly, the chapter on querying XML databases was enough to whet my appetite, but it was mostly on the representation of queries (useful, to be sure, but confusingly presented), had little about efficiency considerations (surely of paramount importance when discussing queries), and presented as "algorithms" methods that are so unrefined and simplistic that they're better labeled "query methodologies."To be fair, I haven't been all that impressed with the other XML books I've been skimming...
Is the review positive or negative?
