Do you have practical experience using NoSQL systems for data storage?

Yes, I have experience using NoSQL systems such as MongoDB and Redis for data storage. NoSQL databases are suitable for storing unstructured or semi-structured data, providing schema flexibility and scalability.

For example, in C# with MongoDB, you can work through the official driver:

using MongoDB.Driver;

var client = new MongoClient("mongodb://localhost:27017");
var database = client.GetDatabase("testdb");
var collection = database.GetCollection<BsonDocument>("users");

var document = new BsonDocument { { "name", "Ivan" }, { "age", 30 } };
collection.InsertOne(document);

var filter = Builders<BsonDocument>.Filter.Eq("name", "Ivan");
var user = collection.Find(filter).FirstOrDefault();

This approach allows for efficient handling of dynamic data structures and quick application scaling.
