Relational DB: The Next-Generation
Over the last decade, there has been a lot of excitement around databases that are decidedly NOT relational. We have seen a rise in popularity around Key-Value stores like Memcached and Redis due to their pubsub system, and a movement toward “NoSQL” databases that offer greater flexibility for storing objects of widely-varying shapes.
The great news is that hosted relational databases have caught up! Starting with PostgreSQL 9.4 and MySQL 5.7 support JSON as a column type, first-class pubs systems, full-text search and more!
