Type inference in the polymorphic relational algebra
Summary: Polymorphic typing for relational algebra via bespoke "type formulas" and an algorithm that computes an expression's principal type. The principal type concisely characterizes all attribute-set assignments making the expression well-typed and its output schema; includes complexity and monadic-logic/polymorphism analysis.
