Ive always wondered this but never had the chance to research it. What sort of algorithms are use in SQL?

Question

Naturally you search and compare for basic statements, what search algorithms? Sorting? and for other functions like Join's etc.
I know there is no clear cut answer to this questions but the idea is to gather a general idea of what sort of methods SQL uses to carry out its work.
