The "it's always S-Q-L and never `sequel`" is IBM's fault and an early trademark infringement issue in computing. (IBM was told it couldn't call it "SEQUEL" by an aircraft company.)
>> The forerunner of SQL, which was called SEQUEL (for Structured English Query Language), first emerged in the specifications for System R, IBM’s experimental relational database, in the late 1970s. However, two other products, with various names for their query language, beat IBM to the marketplace with the first commercial relational database products: Relational Software’s Oracle and Relational Technology’s Ingres. IBM released SQL/DS in 1982, with the query language name shortened to “SQL” after IBM discovered that “SEQUEL” was a trademark of the Hawker-Siddeley Aircraft Company. When IBM released its next generation RDBMS, called DB2, the SQL acronym remained. To this day, you will hear the name pronounced as an acronym (S-Q-L) and as a word (see-quel), and both are considered correct pronunciations.
I was hoping for a bit more interesting or detailed story.
Somewhere, I believe in an HN comment, I saw a Postgres developer say that one of the biggest regrets of the project naming was capitalizing that "shared S".
I always interpreted it as Post-gr-S-Q-L. Which is basically the same thing but makes more sense to me because it’s as if the name had a silent “e”.
I’m half joking but it might alleviate people from being confused.
The name confusion is all IBM's fault.
> Chamberlin and Boyce's first attempt of a relational database language was Square, but it was difficult to use due to subscript notation. After moving to the San Jose Research Laboratory in 1973, they began work on SEQUEL. The acronym SEQUEL was later changed to SQL because "SEQUEL" was a trademark of the UK-based Hawker Siddeley Dynamics Engineering Limited company.
