PFL - Persistent Functional Language


PFL (Persistent Functional Language) was developed during the 1990s by Alex Poulovassilis, Carol Small, Pete Newson, Swarup Reddi and David Sutton at Birkbeck, and Simon Courtenage at the University of Westminster. Initially, PFL aimed to combine the respective advantages of the Functional Data Model (see right) with the deductive capabilities of logic-based languages. Subsequently, we extended PFL with Event-Condition-Action (ECA) rules. This work was funded by a series of research grants in database languages.
