Query: Extremely "Salesy". Not In-Depth At All

This book is okay to read in your spare time if you lack ANY other material. But I would strongly advise against purchasing it as a reference. I normally hold high expectations of QUE books, but this one totally missed the mark. Almost half the back is one long advertisement for the various outside options available for Unicenter. It would be like buying a book on Microsoft Windows where half the pages were devoted to advertising other Microsoft products. Hopefully, major improvements will be made in future revisions.
