چکیده

The realization of truely heterogeneous database systems is hampered among others by two obstacles. One is the unsuitability of traditional transaction models, this has lead to the proposal of a new more flexible transaction model. Th.e second is the fact that none of the existing language and system support such a flexible model. This paper addresses these two issues by proposing a logic approach to the integration of database systems.

Transaction Speciication in Multidatabase Systems Based on Parallel Logic Programming

The integration of multiple autonomous and heterogeneous database systems into one multidatabase system requires a powerful language which serves both for specifying queries and transactions. In our previous work we proposed a Prolog-based language for specifying queries in multidatabase systems. In this paper, we have introduced a parallel Prolog-based query language which serves well as a con...

A Language Multidatabase System

Rapid growth in the area of Multi Database Systems (MDBSs), which involve both the access of global data and distributed transaction processing, has created a need for programming languages that provide communication reliability and powerful synchronization. In this paper, we rst present the requirements of MDBSs, then explain the V P L (Vienna Parallel Logic) programming language and its featu...

We present an execution model for distributed transactions that can be employed for multidatabase systems. We use the Flex Transaction model that has been proposed as a highly general and exible tool for the speciication of distributed transactions and extend it by allowing nested and possibly recursive transaction speci-cations. We show how a given transaction speciication and its execution mo...

A rule-based evaluation of ladder logic diagram and timed petri nets for programmable logic controllers

This paper describes an evaluation through a case study by measuring a rule-based approach, which proposed for ladder logic diagrams and Petri nets. In the beginning, programmable logic controllers were widely designed by ladder logic diagrams. When complexity and functionality of manufacturing systems increases, developing their software is becoming more difficult. Thus, Petri nets as a high l...
