RavenDB installation and use

RavenDB is a NoSQL database based on document databases, running on the. NET platform and providing scalable and high-performance data storage. The following is a detailed introduction to the installation and use of RavenDB: 1. Install RavenDB: a. Open RavenDB official website（ https://ravendb.net/ ）And download the Windows installation program. b. Double click on the installation program and follow the prompts to install it. Select the default installation option. c. After installation, RavenDB will start a service locally, using port 8080 by default. 2. Create a data table: a. Open the RavenDB management console at the address http://localhost:8080 . Select the Databases tab above the console interface and click the "New Database" button. b. Enter the database name, such as' MyDatabase ', and click the' Create 'button. RavenDB will create a new database for you. 3. Data insertion, modification, query, and deletion: a. Insert data: i. Use the programming language of your choice (such as C #) to reference the RavenDB client library and establish a database connection. Ii Create an entity object, such as a Person class object. Iii. Use the Session object in the RavenDB client library to store the entity Object storage in the database. The example code is as follows: csharp using(var session = store.OpenSession()) { var person = new Person { Name = "John Doe", Age = 30 }; session.Store(person); session.SaveChanges(); } b. Query data: i. Use RavenDB's Query language (RQL) or LINQ to query data. The sample code is as follows: csharp using(var session = store.OpenSession()) { var persons = session.Query<Person>() .Where(x => x.Name == "John Doe") .ToList(); } c. Modify data: i. Query the data to be modified and update the corresponding attributes. Ii Save changes to the database. The example code is as follows: csharp using(var session = store.OpenSession()) { var person = session.Load<Person>("persons/1"); // Load the person by document ID person.Age = 33; // Update the age property session.SaveChanges(); // Save changes to the database } d. Delete data: i. Obtain the data to be deleted through query or loading methods. Ii Use the Delete method of RavenDB's Session object to delete data. The example code is as follows: csharp using(var session = store.OpenSession()) { var person = session.Load<Person>("persons/1"); // Load the person by document ID session.Delete(person); // Delete the person document session.SaveChanges(); // Save changes to the database } This is the basic introduction to the installation and use of RavenDB. Through these steps, you will be able to install RavenDB, create a database, and use C # code to perform data insertion, modification, query, and deletion operations.
