Dear friends,
Here is the sentence I'd like to ask you about:
"The progress achieved in the area of database technologies is particularly based on the relational model suggested by E. Codd at the turn of the 60-s and 70-s of the XX century.
I've hot two questions:
1) Is the expression "at the turn of" grammatically correct here (the intended meaning is that the relational model mentioned in the sentence was offered at the end of the 1960-s and the beginning of the 1970-s; at the turn of = boundary?)
2) Is it correct to write "1960-s" meaning "the nineteen sixties" and "1970-s" meaning "the nineteen seventies"?
Thanks a lot
