Decimal numbers shown to be inadequate -- future is cornflakes.
Make just as much sense as the headline.
The relational model is just that -- an abstract model which defines how data can be represented.
A relational database is a piece of software that cofroms to the rules of hte relational model. There are no constaints on hte implmentation, and, indeed modern relational databases are usually multi-htreaded, multi-process and in many cases multi machine beasts. Internally map-reduce is often used to optimise and parallelize query processing.
SQl itself is ver far from dead and is constanly evolving (new verbs like COALESS are appearing all the time) my main gripe with SQL is that its the most difficult grammer to write a parser for -- the number of places where a select statement can appear inside a select statement is staggering.
This is not to say that RDMS is the only valid approach, new technoligies like googles "Big Table" are impressive, and, there are still many thousand "old technoligy" databases like IMS, IDMS out there. I wonder if anyone is still using TOTAL?
These "Relational Is Dead" stories are getting as tiresome as "The Mainframe is Dead".
