The theory of relational databases has much in common withthe mathematical structures central to the Z notation. Manyauthors have noted these connections in the past, but thedevelopment of the Z Standard has provided a more naturalway of making these links explicit. In this paper we exploreextensions to the schema calculus that may help to model thefamiliar relational algebra operations in a clear way. Potentialareas of application for this work include pedagogy,practical database design, and helping to point the way towardsa more general means for defining a broader class ofschema calculus operations.
