Mar 15 '18 at 22:08 comment added PJTraill Perhaps the syntactic monoid of a formal language is relevant, though it is not mentioned in the answers. Though I expect, like many answers, that it is relevant to computation in general rather than database computations.

Feb 11 '13 at 21:31 comment added Steven Stadnicki I would strongly dispute the contention that monoids and semi-groups are both considered 'useless theoretical constructs', as both have quite a bit of utility within mathematics itself as well, both in category theory and for modeling various other algebraic structures. What branch of mathematics do you come from that considers semigroups 'useless'?

Feb 11 '13 at 16:49 comment added vzn agreed, find it surprising twitter is dinking around in these areas, its rather abstract. the main idea seems to be reusable components for a Mapreduce-like system. algebird seems to have "spun off" from scalding. heres a talk on scalding. however it doesnt mention the algebraic objects. possibly they can be used as data object primitives/types for manipulation in the dataflows, which are also mapped into functional programming style....
