Redmond also colloquially refers to the product Microsoft SQL Server as just SQL (pronounced &quot;sequel&quot;), as in, &quot;We&#x27;re trying sell more SQL licenses,&quot; or, &quot;Is the backing DB for your SAP installation Oracle or SQL?&quot;<p>This has led to some confusion.<p>Additionally, as I pointed out in a sibling comment up the chain somewhere, SQL is an abbreviation of the original acronym, SEQUEL, for Structured English QUEry Language. It seems with this provenance that the &quot;sequel&quot; pronunciation is more historically correct.
