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.

Exploring Azure NoSQL databases

In Azure, there are a few options for deploying NoSQL databases, from deploying an open source database such as MongoDB, Cassandra, or Neo4j running in a virtual machine IaaS, through HBase databases in the Azure HDInsight service, to Azure Cosmos DB.

Azure Cosmos DB is the main Azure offering to implement a NoSQL database. It’s the NoSQL database most asked about in the questions of the DP-900 test and is the most used in modern projects, so let’s explore it next.

Exploring Azure Cosmos DB

In this section, we will learn about the concepts of Azure Cosmos DB, and in Chapter 10, Provisioning and Configuring Non-Relational Data Services in Azure, we will explore it further by performing its provisioning and configuration.

Azure Cosmos DB is a multimodal, globally distributed NoSQL database system on Azure, which means that depending on its setting, it may have different operating characteristics and infrastructure architecture...
