Tell me about your experience working with the MongoDB database and how you interacted with it in projects

In projects with MongoDB, I interacted through the official Java driver and using Spring Data MongoDB. The main operations included:

• Connecting to the database and configuring connection parameters.
• Creating and using repositories for CRUD operations.
• Executing queries with filters and aggregations.
• Indexing collections to optimize queries.

Example of using Spring Data MongoDB:

@Document(collection = "users")
public class User {
    @Id
    private String id;
    private String name;
    private int age;
    // getters and setters
}

public interface UserRepository extends MongoRepository<User, String> {
    List<User> findByAgeGreaterThan(int age);
}

This approach allows working conveniently with documents as Java objects, simplifying development and maintenance.
