To get the most out of this book
Theis book has multiple SOQL query code blocks throughout the chapters, and you are strongly encouraged to follow along and try them in a Developer Edition of Salesforce. For chapters that may appear to be theoretical in nature, for example, ones on data governance, I would encourage you to think of your own current or past organizations and try to apply the principles learned in the chapters, including the practical aspects of these topics, for example, metrics or KPIs for data quality.
The book assumes an understanding of basic Salesforce functionality, so at times, advanced topics may be challenging to grasp in the absence of the required knowledge.
