Abstract
We characterise compositional homomorphims of relational structures. A study of three categories of such structures - viewed as multialgebras - reveals the one with the most desirable properties. We study also analogous categories with homomorphisms mapping elements to sets (thus being relations). Finally, we indicate some consequences of our results for partial algebras which are special case of multialgebras.
