Who should read this book
This book is designed to help experienced T-SQL practitioners become more knowledgeable and efficient in this field. The book’s target audience is T-SQL developers, DBAs, BI pros, data scientists, and anyone who is serious about T-SQL. Its main purpose is to prepare you for real-life needs, as far as T-SQL is concerned. Its main focus is not to help you pass certification exams. That said, it just so happens that the book covers many of the topics that exams 70-461 and 70-464 test you on. So, even though you shouldn’t consider this book as the only learning tool to prepare for these exams, it is certainly a tool that will help you in this process.
This book assumes that you have at least a year of solid experience working with SQL Server, writing and tuning T-SQL code. It assumes that you have a good grasp of T-SQL coding and tuning fundamentals, and that you are ready to tackle more advanced challenges. This book could still be relevant to you if you have similar experience with a different database platform and its dialect of SQL, but actual knowledge and experience with SQL Server and T-SQL is preferred.
