System-R (which came from San Hose) and PRTV (the Peterlee Relational Test vehicle). As I understand it SQL came from System-R and the optimizer (amongst other things) came from PRTV.
PRTV (https://en.wikipedia.org/wiki/IBM_Peterlee_Relational_Test_Vehicle_(PRTV)[1]) did not use SQL, and was never a released product, except with a graphical add-on which was sold to two UK local authorities for urban planning. So there are (and always have been) different ways to send requests to a relational DB, it is just that SQL won the day. -------- [1] https://en.wikipedia.org/wiki/IBM_Peterlee_Relational_Test_Vehicle_(PRTV)
