This book supplements my presentation at the Omaha R User Group on Thursday, April 4, 2019. If you develop Shiny Applications and your back end is a relational database, then this book is for you. The demos and code snippets are written in T-SQL, Microsoft SQL Server dialect of SQL, but the core concepts are applicable across all RDBMS systems. Data Scientists using R are the primary audience. Database Developers, BI Developers, Software Engineers, Data Analysts and Managers wanting to learn more about Shiny Database applications will also benefit from the material.
