Here, we will first create the data model and map the attributes to the attributes in a DynamoDB table. The .Net SDK provides built-in support for the object persistence model, so you don't need to do anything else. Annotations can be used to perform the mapping of data, as shown in the following code:

[DynamoDBTable("product")]
    public class Product
    {
        [DynamoDBHashKey]   // Hash key.
        public int id { get; set; }
        [DynamoDBRangeKey]   // Range key.
        public string type { get; set; }
      ...
