I purchased this ebook since it was once on a suggested examining checklist for varied DB2 UDB Certifications. I had already had good fortune with of the opposite ideas so i thought this is able to be beneficial besides. i could not were extra wrong.

After studying Sanders DB2 learn advisor for the basics (Test #700) and passing the examination, the applying Developer used to be the following logical step. I had already taken a pattern try and approximately handed so i did not have a lot to visit go this CERT. After studying this e-book I query no matter if I obtained adequate out of it to go yet.

The first challenge with this ebook, and it really is my fault for now not checking, is that the 1st six chapters is proper to the basics examination and never the appliance improvement examination. because the basics are a pre-requisite a few may possibly say it belongs right here. i do not agree and used to be disillusioned. i'm going to get to the second one part in a minute. The 3rd part contained bonus fabrics which are past the scope of the examination. that's high-quality with me simply because a minimum of it was once similar fabric. whereas studying the second one part in spite of the fact that, correct smack dab in the course of it, used to be a bankruptcy at the Administrative API. The written target states, "The Administrative API isn't really lined within the DB2 software improvement Certification exam." My query, what's it doing right here? If something it may well were installed the final part. the most aspect is this is indicative of the association of the fabrics inside every one bankruptcy in addition. whereas examining the second one component to the booklet i discovered sections of textual content that have been copied from in the e-book and repeated. This wasn't performed to reaffirm an issue yet appeared that the author's motive was once to exchange it later with various textual content. the matter used to be that it was once by no means replaced and was once simply undeniable mistaken info. This is going past the concept of typos and is unacceptable for a e-book of this nature. one other challenge is that this publication contained no assessment questions and no pattern try questions and but it's alleged to be thought of a certification advisor. whilst i am getting ready for an examination i admire to learn a few fabric after which get suggestions to my point of knowing ahead of relocating on. afterward it supplies me a follow-up examine checklist to study susceptible parts.
