A Knowledge-Based Perspective Of TheDistributed Design Of Object OrientedDatabases

The performance of applications on Object Oriented Database Management Systems (OODBMSs) is strongly affected by Distributed Design, which reduces irrelevant data accessed by applications and data exchange among sites. In an OO environment, the Distributed Design is a very complex task, and an open research problem. In this work we propose a knowledge based approach to the fragmentation phase of the distributed design of object oriented databases. In this approach, we will show a rule-based implementation of an analysis algorithm from our previous work and propose some ideas towards the use of Inductive Logic Programming (ILP) to perform a knowledge discovery/revision process using our set of rules as background knowledge. The objective of the work is to uncover some previously unknown issues to be considered in the distributed design process. Our main objective here is to show the viability of performing a revision process in order to obtain better and better fragmentation algorithms. We do not intend to propose the best fragmentation algorithm ever possible. We concentrate here on the process of revising a DDOODB algorithm through Knowledge Discovery techniques, rather than only obtaining a final optimal algorithm.
