Propagation Rule Compiler : Technical Documentation
نویسندگان
چکیده
The Propagation Rule Compiler (PROP) is a tool developed within the ES-PRIT III project IDEA (Intelligent Database Environment for Advanced Applications). It 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 speciic updating transaction has been issued. PROP has been integrated as a subcompo-nent into Bonn's Chimera Prototyping Tool (CPT). The purpose of this document is to provide the technical documentation of the rule compilation process. This report has been issued to the ESPRIT III project 6333 (IDEA) as deliverable IDEA.DE.22.O.005.

This document evaluates the Propagation Rule Compiler (PROP) which has been developed at the Univ. of Bonn and continuously improved within the last three years. The purpose of PROP is to analyze all deductive rules of a given Chimera schema implementing derived concepts (attributes, classes, views, and constraints). Based on this analysis it generates triggers which are able to compute all imp...

has extended the address space accessible to applications beyond the traditional 32-bit address space. This new address space is referred to as 64-bit virtual memory and requires a 64-bit pointer for memory access. The operating system has an additional set of new memory allocation routines that allows programs to allocate and release 64-bit memory. In OpenVMS Alpha version 7.0, this set of rou...
