Query: The one reference you need for Informix

Of all the books I have read about Informix, Flannery's is the easiest to use. The topics are well organized and cross-referenced, which helps me find what I need quickly. In addition, the book has a web site which keeps it current. Also, the book's numerous examples make it easy for me to apply the knowledge it contains. I love the formatting and the way that I don't have to read hundreds of pages to find the answers. Well done!
