The 70-762 exam tests your knowledge about developing databases in Microsoft SQL Server 2016. To successfully pass this exam, you should know how to create various types of database objects, such as disk-based and memory-optimized tables, indexes, views, and stored procedures, to name a few. Not only must you know how and why to develop specific types of database objects, but you must understand how to manage database concurrency by correctly using transactions, assigning isolation levels, and troubleshooting locking behavior. Furthermore, you must demonstrate familiarity with techniques to optimize database performance by reviewing statistics and index usage, using tools to troubleshoot and optimize query plans, optimizing the configuration of SQL Server and server resources, and monitoring SQL Server performance metrics. You must also understand the similarities and differences between working with databases with SQL Server on-premises and Windows Azure SQL Database in the cloud.
The 70-762 exam is focused on measuring skills of database professionals, such as developers or administrators, who are responsible for designing, implementing, or optimizing relational databases by using SQL Server 2016 or SQL Database. In addition to reinforcing your existing skills, it measures what you know about new features and capabilities in SQL Server and SQL Database.
To help you prepare for this exam and reinforce the concepts that it tests, we provide many different examples that you can try for yourself. Some of these examples require only that you have installed SQL Server 2016 or have created a Windows Azure subscription. Other examples require that you download and restore a backup of the Wide World Importers sample database for SQL Server 2016 from https://github.com/Microsoft/sql-server-samples/releases/tag/wide-world-importers-v1.0. The file to download from this page is WideWorldImporters-Full.bak. You can find documentation about this sample database at Wide World Importers documentation, https://msdn.microsoft.com/library/mt734199(v=sql.1).aspx.
This book covers every major topic area found on the exam, but it does not cover every exam question. Only the Microsoft exam team has access to the exam questions, and Microsoft regularly adds new questions to the exam, making it impossible to cover specific questions. You should consider this book a supplement to your relevant real-world experience and other study materials. If you encounter a topic in this book that you do not feel completely comfortable with, use the “Need more review?” links you’ll find in the text to find more information and take the time to research and study the topic. Great information is available on MSDN, TechNet, and in blogs and forums.
