Who This Book Is Not For

This book is not written for “big data” professionals. To be clear, even large corporations like Doordash, Discord, and the owners of The Financial Times and The New York Times (all previous customers of ours) do not qualify as big data companies. As a rule of thumb, the big data label applies to data architectures with raw input that exceeds 100 GB per day.

No doubt, many elements of this text map onto the big data workflow, especially since warehouses support all sorts of tables, not just, say, event streams. However, our aim is to focus on the central pillars of a modern data stack, so that the widest set of readers can readily benefit from the information herein. In this spirit, we forgo recommendations for mega‐scale architectures.

      This book is not for AI‐enabled teams and does not cover AI workflows, machine learning models, or real‐time operational use cases. Instead, its goal is to provide best practices for building and maintaining a robust data analytics stack (i.e. the analytics foundation on which an AI workflow can be built).

      If you are a small business that can run everything with Quickbooks and Excel, that ability is great. Data is important for all companies, but if these tools are already serving you well, the book may not offer helpful guidance. If you start exceeding the data capacity of Excel or bring in a data source that needs to be in a database to be analyzed, then keep reading.

Who Wrote the Book

      This book was written by Dave Fowler and Matt David.

      Dave Fowler has worked in BI for over a decade, and has always looked for ways to JOIN teams ON data . He wants to enable any working professional (not just data analysts) to explore and understand their data. As the founder and CEO of Chartio, Dave has spent the last 11 years leading the development of a self‐service BI product that aims to do just that. Chartio's suite of tools make it easy for anyone at a data‐driven business to browse their schemas, merge various data sources, and produce beautiful dashboards. In March 2021, Atlassian acquired Chartio and is integrating it into their platform.

Matt David has worked in product management and education for eight years. As data becomes a necessary skill for more and more jobs, he passionately advocates for data literacy among the workforce. As the current head of The Data School, he oversees the production of free, online resources focused on leveraging data within companies. Recent book topics include SQL optimization, data governance, and common analysis biases. Dave started The Data School, and together he and Matt have grown it into an important free resource for the data community. He previously worked at Udacity and General Assembly teaching analytics.

      Dave and Matt decided to co‐write this book after seeing how many people struggle when constructing data stacks and then trying to use them. This book was created with the support of many employees at Chartio. They graciously provided insights into how customers model their data and collected frequently asked data‐infrastructure questions. Their contributions guided the production of this text.

Who Edited the Book

      This book was reviewed and edited by Emilie Schario, Mila Page, and David Yerrington. Emilie is the head of data at Netlify and previously helped build Gitlab's entire data organization. She regularly writes and speaks on all things related to modern data. Mila is a developer relations advocate at dbt Labs, the makers of dbt (data build tool). She helps data professionals learn and apply modern analytics‐engineering practices, and is an organizer for Coalesce, the dbt Community’s annual conference. David is a Data Science Consultant and was the Global Lead Data Science Instructor at General Assembly. He helps people around the world better leverage their data. Emilie, Mila, and David have shaped the narrative and content of this book. Their (sometimes) line‐by‐line feedback has ensured that we can proudly stand behind our recommendations.

Influences

We've drawn on several sources of information and opinion when writing this text. While at Chartio, we worked with hundreds of modern cloud‐based customers. We've collected, implemented, and refined these practices ourselves, and through writing this book, vetted them further with partners and customers. We've also learned from the data community through dataschool.com, blogs like Tristan Handy's, and data‐focused slack communities.

      And lastly, it's worth noting and thanking some classic books that informed the previous generation of warehousing toolkits. We honor them by echoing their terminology and best practices wherever possible:
