Overview of this book

Microsoft SQL Server 2017 is a milestone in Microsoft's data platform timeline, as it brings in the power of R and Python for machine learning and containerization-based deployment on Windows and Linux. This book prepares you for advanced topics by starting with a quick introduction to SQL Server 2017's new features. Then, it introduces you to enhancements in the Transact-SQL language and new database engine capabilities before switching to a different technology: JSON support. You will take a look at the security enhancements and temporal tables. Furthermore, the book focuses on implementing advanced topics, including Query Store, columnstore indexes, and In-Memory OLTP. Toward the end of the book, you'll be introduced to R and how to use the R language with Transact-SQL for data exploration and analysis. You'll also learn to integrate Python code into SQL Server and graph database implementations as well as the deployment options on Linux and SQL Server in containers for development and testing. By the end of this book, you will be armed to design efficient, high-performance database applications without any hassle.

Chapter 16. Graph Database

In the recent years, the data landscape has changed significantly: massively structured and unstructured data is being generated from various sources. Applications and services are being developed with agile methodologies more frequently than ever, the data changes being fast and significant. Scalability requirements are also very important. Relational database management systems are not designed to handle all these challenges. Therefore, enterprises use NoSQL database solutions, which are more appropriate for new data requirements.

Graph databases belong to the NoSQL databases family. They have only existed for a few years and are used for storing and querying highly connected data, usually connected with many-to-many relations. SQL Server 2017 offers graph database capabilities in a feature called SQL Graph.

This chapter is divided into the following three sections:

  • Introduction to graph theory and graph databases
  • SQL Graph in SQL Server 2017
  • Limitations in the current...
