Overview of this book

Passing the DP-900 Microsoft Azure Data Fundamentals exam opens the door to a myriad of opportunities for working with data services in the cloud. But it is not an easy exam and you'll need a guide to set you up for success and prepare you for a career in Microsoft Azure. Absolutely everything you need to pass the DP-900 exam is covered in this concise handbook. After an introductory chapter covering the core terms and concepts, you'll go through the various roles related to working with data in the cloud and learn the similarities and differences between relational and non-relational databases. This foundational knowledge is crucial, as you'll learn how to provision and deploy Azure's relational and non-relational services in detail later in the book. You'll also gain an understanding of how to glean insights with data analytics at both small and large scales, and how to visualize your insights with Power BI. Once you reach the end of the book, you'll be able to test your knowledge with practice tests with detailed explanations of the correct answers. By the end of this book, you will be armed with the knowledge and confidence to not only pass the DP-900 exam but also have a solid foundation from which to embark on a career in Azure data services.

Use cases

An RDBMS uses SQL as its default language. In general, use cases that can be applied to Azure SQL Database can also be applied to Azure Database for MySQL, PostgreSQL, and MariaDB, depending on which technology you want to use or what your application has already been developed on.

Therefore, instead of showing use cases of each of these technologies, in this section, I will present the reasons for opting for Azure SQL Database.

Important note

Whether you use a SQL or NoSQL database for a particular use case is one of the most important questions for a data architect. You will complete your knowledge in Chapter 9, Exploring Non-Relational Data Offerings in Azure, where we will discuss Azure NoSQL databases and list the main reasons for using a NoSQL database.

The big difference between a relational database and a non-relational database is the schema definition, which is defined at the beginning of the project on the relational database.
