Did you know the purely relational dogma of SQL was already abandoned in 1999? The last SQL standard that was limited to the relational idea was SQL-92.
From SQL:1999 onwards, the SQL language was extended with non-relational operations and non-relational data structures. As much as this move was discussed at that time, it took decades until database vendors caught up with this idiomatic change. Many SQL users haven’t heard of it until today.
This talk provides the big picture on the evolution of the SQL standard and introduces some selected modern SQL features by example. You will see that SQL has changed as much as our requirements have changed over the past decades.
