Data Vault Ensemble Modeling

Getting it Right

Kent Graziano, Snowflake Computing

Yes, we still need data models and data modelers! A good data model, done right the first time, can save you time and money. We have all seen the charts on the increasing cost of finding a mistake/bug/error late in a software development cycle. Would you like to reduce, or even eliminate, your risk of finding one of those errors late in the game? Of course you would! Who wouldn’t? Nobody plans to miss a requirement or make a bad design decision (well nobody sane anyway). No data modeler or database designer worth their salt wants to leave a model incomplete or incorrect. So what can you do to minimize the risk and improve the quality and usefulness of your models and designs?

In this talk I will give you my top tips for a simple, repeatable process for reviewing your data models that I have been using for over 20 years.  It is one that even a non-modeler could follow. I will share my checklist of what to look for and what to ask the data modeler (or yourself) to make sure you get the best possible data model while avoiding analysis paralysis.
