6. Dynamo (storage system) - Wikipedia

   en.wikipedia.org/wiki/Dynamo_(storage_system)

   Dynamo is a set of techniques that together can form a highly available key-value structured storage system [1] or a distributed data store. [1] It has properties of both databases and distributed hash tables (DHTs). It was created to help address some scalability issues that Amazon experienced during the holiday season of 2004. [2]

7. Document-oriented database - Wikipedia

   en.wikipedia.org/wiki/Document-oriented_database

   Document stores use the metadata in the document to classify the content, allowing them, for instance, to understand that one series of digits is a phone number, and another is a postal code. This allows them to search on those types of data, for instance, all phone numbers containing 555, which would ignore the zip code 55555.
