Fifty Years of Databases (2012)
wp.sigmod.org"the origins of the standard architecture for OLTP, which is row-based, and says it’s no longer optimal for any of the use cases that it is applied to. He proceeds to describe some research he has done, showing that row-based databases spend about 90 percent of their time acquiring and releasing locks, buffer management, and other activities that could be characterized as overhead in comparison to main task of reading and writing data. These results, which in Stonebraker’s view are intrinsic to the row-based architecture, require a new architecture to overcome. The discussion proceeds to a new database architecture, known as “NewSQL” or “NewOLTP,” which is single-threaded, lock-free, doesn’t require disk I/O in the critical path, and can scale out to a large multiple node cluster. Stonebraker criticizes the eventual consistency model that some NoSQL distributed systems employ and he defends the ACID guarantees as a superior model."

he's describing voltdb (that he built)
plus MemSQL, a YC company =)
Two others are Google Spanner [1] and FoundationDB [2].

>> In addition, IDS and other network systems encoded what we now think of as the “joins” between different kinds of records as part of the database structure rather than specifying them in each query. --
This is basically Neo4j and other graph databases.

Those "R1", "R2"s in the picture... those are your "joins".
IDS: The first NoSQL data store? In 1962 (sigmod.org)

Fifty Years of Databases (2012)Right. We changed it back.
Submitters: please don't editorialize in titles.
Thanks.
I flag submissions with questionable titles. I believe this is the right thing to do, but what about after the title is changed? Does it still show up in a queue? Should I unflag submissions if I notice the title is changed?
Sure, if the reason why you flagged a story gets fixed, unflagging it is a good idea.
So noSQL was absoleted by relational databases in '80
It's hard to say, really. People were using a lot of non-SQL (read: row-based) databases well into the 1990s.
