Overview of this book

Microsoft SQL Server 2016 is considered the biggest leap in the data platform history of the Microsoft, in the ongoing era of Big Data and data science. This book introduces you to the new features of SQL Server 2016 that will open a completely new set of possibilities for you as a developer. It prepares you for the more advanced topics by starting with a quick introduction to SQL Server 2016's new features and a recapitulation of the possibilities you may have already explored with previous versions of SQL Server. The next part introduces you to small delights in the Transact-SQL language and then switches to a completely new technology inside SQL Server - JSON support. We also take a look at the Stretch database, security enhancements, and temporal tables. The last chapters concentrate on implementing advanced topics, including Query Store, column store indexes, and In-Memory OLTP. You will finally be introduced to R and learn how to use the R language with Transact-SQL for data exploration and analysis. By the end of this book, you will have the required information to design efficient, high-performance database applications without any hassle.

If we needed to change the structure of a memory-optimized table, we had to resort to dropping and recreating the object with the new, updated structure.

For many developers/customers, this was a deal breaker. Being able to add and remove columns or indexes is something that every SQL Server developer is used to without any such restrictions. Especially, with the advent of agile software development and similar development strategies such as continuous integration, making changes to software applications is something many developers strive towards.

Now, with SQL Server 2016, it is possible to do just that. We will be continuing this chapter using the same database as in Chapter 11, Introducing SQL Server In-Memory OLTP, creating a simple memory-optimized table:

USE master
