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.

DDL, DML, and programmable objects


As a developer, you are often also responsible to create database objects. Of course, in an application, you also need to insert, update, and delete the data. In order to maintain data integrity, enforcing data complies with business rules, you need to implement constraints. In a quick review of the data definition language (DDL) and data modification language (DML) elements, the following statements are presented:

  • CREATE for creating tables and programmatic objects

  • ALTER to add constraints to a table

  • DROP to drop an object

  • INSERT to insert new data

  • UPDATE to change existing data

  • DELETE to delete the data

In a SQL Server database, you can also use programmatic objects. You can use triggers for advanced constraints or to maintain redundant data like aggregated data. You can use other programmatic objects for data abstraction, for an intermediate layer between the actual data and an application. The following programmatic objects are introduced here:
