Overview of this book

RavenDB is a second generation document database written in .NET, offering a flexible data model designed to address requirements coming from real-world systems. 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.

Time for action – querying a temporary index


To illustrate how RavenDB uses existing temporary indexes, we will recall the Query<Country>() method we created in the previous section. Also we will create another query using the same parameter, which will use the same temporary index. Then you will analyze the RavenDB logs in the RavenDB prompt window and visualize the Management Studio Indexes screen.

  1. Open RavenDB Management Studio, select the Indexes tab of the World database and ensure that Temp/Countries/ByArea_RangeSortByArea index exists. If not, follow all the steps of the previous section to create the temporary index.

  2. Open the RavenDB_Ch04 solution.

  3. Add the following code snippet to the Main() method in the Program class:

  4. Save all the files, build and run the solution.

  5. Open the RavenDB prompt window and analyze the RavenDB logs.

  6. In Management Studio, select the World database and click on the Indexes tab to display the Indexes screen and verify that there are no new temporary indexes...
