Abstract
We describe how a functional database programming language can be extended with transactions and EGA-rules. Fundamental requirements of such an extension are that the declarative semantics of the language not be compromised, that the syntax of the language not be disrupted unduly, and that impedance mismatch problems be avoided. We define what we mean by events, conditions and actions and describe the semantics of EGA-rules with reference to event detection, parameter-binding, transaction scheduling and abort handling. We define the execution semantics for the EGA System in the language itself. These semantics form the basis of our implementation of the EGA System.
