A blog post clarifies the common confusion between relation algebra (a mathematical/logical structure equivalent to FOL^3) and relational algebra (Codd's foundation for relational databases). The author also notes relation algebra's practical CS applications, notably in the Alloy analyzer.
Background
Relation algebra and relational algebra are distinct concepts from different fields—pure mathematics/logic versus computer science/database theory—yet their similar names cause frequent confusion even in authoritative sources.
