> the fact that technology often comes back around another time in a new form. In this case, it's failed technology. That's what the people who developed these "NoSQL" kluges and those who adopted them don't understand. Non-relational databases like IMS were once popular, but fell out of favor after the advent of RDBMSs, and for very good reasons, which the adopters of Mongo etc. had to rediscover. > For example, along the lines of IBMs IMS, I also recall the MUMPS system and language [1] and I'd be interested to know if the inventors of TileDB were familiar with the history of sparse array interfaces to databases or not, if it influenced their design in any way or it was rediscovered. The "inventors" of these rehashes are generally just as ignorant of history as the users who adopt their "solutions."
