Abstract
This chapter describes the active subsystem of PFL, a functional database programming language (DBPL). We discuss how PFL has been extended with transactions and ECA rules without compromising the confluence of expression evaluation. We describe the support for primitive and composite events, the definition and semantics of ECA rules, and the execution model. To our knowledge, this is the first time that an active subsystem has been added to a functional DBPL.
