It is different from the other document databases around, as with RavenDB you can get up and running in a few minutes, and that includes grasping all the basics. It allows you to build high-performance, low-latency applications with ease and efficiency.RavenDB 2.x Beginner's Guide introduces RavenDB concepts and teaches you everything, right from installing RavenDB, to creating documents, and querying indexes. This book will help you take advantage of powerful, document-oriented NoSQL databases and build a solid foundation on which you can create your .NET applications. This book presents RavenDB, the .NET document-oriented NoSQL database, through a series of clear and practical exercises that will help you to take advantage of this database server. The book starts off with an introduction to RavenDB and its Management Studio. You will then move ahead and learn how to quickly and efficiently build high performance, NoSQL document-oriented .NET applications using the .NET client API or the HTTP REST API. Next, Dynamic and static indexes that use map/reduce to process datasets are covered. You will then see how to create and query these indexes, with the help of detailed examples. You will also learn how to deploy your RavenDB server in a production environment and how to optimize and secure it.With numerous practical examples, RavenDB 2.x Beginner's Guide teaches you everything you need to know for building high performance .NET document-oriented NoSQL databases.

  2. Click on the Method tab and select the GET HTTP method.

  3. In the HTTP Request section, enter this URL: http://localhost:8080/databases/orders/indexes/TotalOrdersPerCustomer.

  4. Click on the green Go! button to send the GET request to the server.

What just happened?

We queried the TotalOrdersPerCustomer index from the Orders database using a GET request addressed to the indexes structure.

The server response is a JSON object that contains the arrays: Results which contains all returned documents by the index and Includes. Also, in the server response, we have two fields: IsStale the value of which is false and the TotalResults the value of which is set to 4 which is the documents count that have been returned by the...
