Overview of this book

The Snowflake Data Cloud is one of the fastest-growing platforms for data warehousing and application workloads. Snowflake's scalable, cloud-native architecture and expansive set of features and objects enables you to deliver data solutions quicker than ever before. Yet, we must ensure that these solutions are developed using recommended design patterns and accompanied by documentation that’s easily accessible to everyone in the organization. This book will help you get familiar with simple and practical data modeling frameworks that accelerate agile design and evolve with the project from concept to code. These universal principles have helped guide database design for decades, and this book pairs them with unique Snowflake-native objects and examples like never before – giving you a two-for-one crash course in theory as well as direct application. By the end of this Snowflake book, you’ll have learned how to leverage Snowflake’s innovative features, such as time travel, zero-copy cloning, and change-data-capture, to create cost-effective, efficient designs through time-tested modeling principles that are easily digestible when coupled with real-world examples.

Expanding from logical to physical modeling

At this stage in the modeling journey—preparing to transform a logical model into a physical one—the use of a modeling tool will make a marked difference in the effort required to generate the final DDL. While this exercise can be done using anything from a sheet of paper to Excel, using a data modeling tool to accelerate the process is encouraged. (See the Technical requirements section of Chapter 1, Unlocking the Power of Modeling for a link to a free trial of SqlDBM—the only cloud-based tool that supports Snowflake and offers a free tier.)

Picking up from the finished logical model from Chapter 8, Putting Logical Modeling into Practice, let’s begin the physical transformation.

Physicalizing the logical objects

Logical models contain all the information needed to transform them into a physical design, but they are not one-to-one equivalent regarding the number of elements. Besides the direct translations...
