DynamoDB
Data structure
DynamoDB is "NoSQL" because it does not support #SQL queries and is non-relational meaning there cannot be JOIN operations via foreign_keys
Although the data is stored as a table, one of the attributes is a key and the rest of the attributes are effectively the values associated with it. Each item in the table is uniquely identifiable by its primary key.
Because DynamoDB is schemaless, neither the attributes or their data types need to be defined beforehand and each item can have its own distinct attributes.
This attribute is known as the primary key.
