DynamoDB
Data structure
Data is stored as a set of key-values in a table
https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/HowItWorks.CoreComponents.html Data is stored as a table of key-value pairs.
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
