Why the SQL vs NoSQL Debate Was Never What You Thought

SQL relational databases, ACID transactions, CAP theorem, and distributed systems — the 48-year story of how a naming mistake became an architectural divide.

Edgar Codd's 1970 relational model paper set the foundation for SQL.

But when Carlo Strozzi coined 'NoSQL' in 1998, he wasn't describing a movement — he was naming a lightweight relational database.

The real shift came with Google's Bigtable (2006) and Amazon's Dynamo (2007), which introduced BASE semantics and horizontal scalability by trading away ACID guarantees. The CAP theorem formalized the tradeoff: you can have Consistency, Availability, or Partition Tolerance, but not all three at once. Then something unexpected happened. Google Spanner proved you could scale ACID. MongoDB added multi-document transactions in 2018 — 48 years after Codd's paper. The divide wasn't about SQL versus NoSQL. It was about what you were willing to sacrifice at scale. And that answer kept changing.
