Propagation Rule Compiler: Technical Documentation

Ulrike Griefahn and Thomas Rath

The Propagation Rule Compiler (PROP) is a tool that aims at supporting developers of Chimera applications during schema design and prototyping. PROP consists of two components: the rule compiler as such and an explanation facility. The task of the explanation facility is to graphically illustrate the logical dependencies established via deductive rules of a given Chimera schema. The purpose of the compilation unit is to generate update propagation triggers from deductive rules. Such triggers are able to automatically compute all implicit changes of a Chimera database once a specific updating transaction has been issued. PROP has been integrated as a subcomponent into Bonn's Chimera Prototyping Tool (CPT). The purpose of this document is to provide the technical documentation of the rule compilation process.
