Dear Askay,
I believe my grey hair allows me to help answer your question. SQL, and its
progenitor SEQUEL, were developed specifically to manipulate relational
databases. It was developed in the early 1970s (equivalent to the historical
bronze age) when the concept of a relational database (see
https://en.wikipedia.org/wiki/Relational_database) and Codd's 12-rules were
being developed (see https://en.wikipedia.org/wiki/Codd%27s_12_rules)
At the time, the concept of a relation database and a programming language
dedicated to manipulating them was revolutionary. The concept was clearly
needed, important, and well used; a commercial version of SQL, Oracle, made
Larry Ellison more than a quarter billionaire.
S, one of the progenitors of R, was developed later. In 1975 by John Chambers,
Rick Becker, Trevor Hastie, and William Cleveland (all of whom, I believe
worked at Bell Labs) developed S as a general programming language. It was NOT
developed specifically for the manipulation of relational databases. S had
modest success in academia. S-Plus, a commercial version of R was developed
fairly recently in 1988 by a company Statistical Sciences. The founder of
Statistical Sciences was R. Douglas Marin who was a professor of statistics at
the University of Washington, Seattle.
S was also the progenitor of R. R was developed by Ross Ihaka and Robert
Gentlemen in 1993, faculty members of the University of Auckland. Given the
ubiquity of R in academia, it is clear that S, much like SQL has been
extraordinarily successful.

Subject: [R] SQL and R
dear Members,
I have recently started studying SQL and MySQL. My
question is, what exactly is SQL used for? That is, whatever can be done by
SQL, like subsetting and filtering of data sets, can also be done by R. What's,
then, the advantage of SQL? It is OK if you tag this question as offtopic, but
I could'nt find any info on the web. Can you please refer me to some online
resources that shed some light on this? Finally, how does SQL complement R? Are
both dependent?
THanking you,
Yours sincerely,
AKSHAY M KULKARNI
