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.

Visual modeling conventions

This chapter will highlight all the semantic elements that will be used throughout the rest of the book. As described earlier, no fixed and universally prescribed standard for drawing modeling diagrams exists. The conventions used here, along with their accompanying visual semantics, are the author’s attempt at simplifying the broad spectrum of modeling concepts and notations into a core set of elements, using the most widely used symbols to represent them. The visual semantics in this book do not conform to any single modeling notation but borrow freely from several leading industry standards. The aim is to provide a modeling language that is both precise enough to accurately reflect technical database details and simple enough for business users to understand the business context that lies beyond the technical specifications.

Unlike those textbooks that separate conceptual, logical, and physical models and force users to convert and adapt one...
