 I wasn't taught SQL in my comp sci database courses in 1981, just hierarchical databases, because "relational is cool theory but not practical for commercial apps". Ironically, I never used a hierarchical database but 5 years later, got a contract writing parsers for IMS, COBOL and PL/1 to generate SQL DDL and migrate data to DB2. 3 comments
I was part of an OO Centre of Competence in the mid-1990s. I wasn't writing much code by then, mostly design and team leader. But I remember a developer telling another that I was an expert in C++, even though I had only read the manual (which I still have). I think it was because I knew how to write compilers and read the book critically through that lens, so was figuring out the point of each feature as I read about it. @EricLawton @blacklight @nf3xn @rrwo @szescstopni @Threadbane much the same in my database class in 1989, I think. SEQUEL got a passing mention in the textbook, but that was about it. :) I know relational theory was discussed, but I long ago chucked the proper terms in favor of SELECT, FROM, WHERE, etc. :) |

@EricLawton @nf3xn @rrwo @szescstopni @Threadbane this is a very interesting insight.
I studied computer engineering two decades later, we were told that SQL had been around since 1974, and most of us assumed that Codd came down the Mount Sinai with the foundations of relational algebra set in stone, and everybody embraced it immediately.
Working on some legacy systems at the beginning of my career, I actually also noticed that DB2 and friends weren't fully embraced until at least the second half of the 1980s.
Same goes for C++ - most of the post-2000 students assumed that after Stroustrup's initial draft C++ and its object oriented paradigm came as a tidal wave on software development, but later on I noticed that most of the software up to at least mid-1990s was still written in earlier languages.
