Five Days Only – Get it Free: A Check List for Doing Data Model Design Reviews

Later this week I travel to Oracle HQ for my first product briefing as an Oracle ACE Director. In celebration of this momentous event, I have decided to give all me readers and followers a gift:

For the next five days (Sept 24 – 28, 2012), my first solo Kindle book will be ON SALE for the low, low price of FREE!

Don’t delay. You can get it here: A Check List for Doing Data Model Design Reviews: Kent Graziano: Kindle Store.

In case you missed my earlier post about the book, here is a brief description:

Tired of crappy data models and whiney data modelers? Need to deliver a high quality design in a short period of time? Need a better way to enforce standards? As part of trying to be more “agile” in my approach to developing databases, I have adopted a concept from the agile world: peer reviews. Before any data model moves from analysis (logical model) into development (physical model), the development team needs to gather to review what the modeler has done. If the model passes the review (almost never on the first round), the physical model is constructed. The physical model is then subjected to a rigorous review as well (including metadata). Only then can DDL be produced and deployed. This guide book will discuss the actual modeling and design process I follow and give you a check list of questions to ask in any model review session. This is a “take no prisoners” approach that has left many a would-be data modeler in a withering heap, but in the end you will have solid models and designs that deliver value.

The book has been doing pretty good (sells for $2.99 normally) but it could do better. 😉 Currently it is #32 if you search for Data Modeling under Kindle ebooks.

Will you help me get it into the top 10?

[ Update: as of Sept 24, 2012 at 12:45 PM CDT the book is now #2 in the Kindle store for Databases! Thanks everyone. Let’s keep it rollin’]

[ Update #2: as of Sept 25, 2012 at 12:45 PM CDT the book is now #1 in the Kindle store for Databases! How long can we keep it there?]

Head on over to Amazon and get it today: A Check List for Doing Data Model Design Reviews.

Thanks a bunch. Hope you can put the information to good use.
