|
|
|
 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
