Guide to NoSQL with Azure Cosmos DB

By: Gaston C. Hillar, Daron Yöndem

Overview of this book

Cosmos DB is a NoSQL database service included in Azure that is continuously adding new features and has quickly become one of the most innovative services found in Azure, targeting mission-critical applications at a global scale. This book starts off by showing you the main features of Cosmos DB, their supported NoSQL data models and the foundations of its scalable and distributed architecture. You will learn to work with the latest available tools that simplify your tasks with Cosmos DB and reduce development costs, such as the Data Explorer in the Azure portal, Microsoft Azure Storage Explorer, and the Cosmos DB Emulator. Next, move on to working with databases and document collections. We will use the tools to run schema agnostic queries against collections with the Cosmos DB SQL dialect and understand their results. Then, we will create a first version of an application that uses the latest .NET Core SDK to interact with Cosmos DB. Next, we will create a second version of the application that will take advantage of important features that the combination of C# and the .NET Core SDK provides, such as POCOs and LINQ queries. By the end of the book, you will be able to build an application that works with a Cosmos DB NoSQL document database with C#, the .NET Core SDK, LINQ, and JSON.

Chapter 2. Getting Started with Cosmos DB Development and NoSQL Document Databases

n this chapter, we will provision a Cosmos DB account that uses the SQL API and we will start working with a document database, its collections, and documents. We will work with Cosmos DB on Azure and we will also learn how to work with the Azure Cosmos DB Emulator. We will work with different tools to interact with our Cosmos DB document database that will be extremely useful for our common development tasks. We will do the following:

  • Understand URIs, read-write and read-only keys, and connection strings
  • Create a new document database with the SQL API
  • Create a new collection
  • Populate a collection with documents
  • Understand automatically generated key-value pairs
  • Understand schema-agnostic features
  • Work with the web-based Azure Cosmos DB Explorer
  • Use Azure Storage Explorer to interact with Cosmos DB databases
  • Work with the Azure Cosmos DB Emulator
