This doesn't mean there are single values corresponding to each key. There can be multiple columns for each key and the key itself is also a column. DynamoDB is "NoSQL" because it does not support #SQL queries and is non-relational meaning there cannot be JOIN operations via [foreign_keys](Foreign_keys_in_SQL.md) ## Usage ## Related notes
