 						- NoSQL databases (aka "not only SQL") are non-tabular databases and store
 						  data differently than relational tables. NoSQL databases come in a
 						  variety of types based on their data model. The main types are document,
 						  key-value, wide-column, and graph. They provide flexible schemas and
 						  scale easily with large amounts of data and high user loads.
 					- explain the application areas of NoSQL #flashcard
+					  id:: 648974ba-b39b-47b7-8b9f-ca9250bef8ba
 						- NoSQL is an alternative, non-traditional DB technology to be
 						  used in large scale environments where (ACID) transactions are not a priority.

 							- There are 3 main properties for distributed management:
 							  1.  Consistency → A data item has the same value at the same time (to
 							      ensure coherency).
