Implementation of Object View Query on a Relational Database

We present the implementation of the query function for the Penguin system. Penguin is an object-oriented database system that supports multiple object views on a relational database. It enables many applications to share a database using di erent object schemata. Also, users can take queries for the Penguin database in their applications, to retrieve objects on the heterogeneous data model. Th...

Object-relational database metrics

Object-relational databases will replace relational systems to become the next great wave of databases because they combine traditional database characteristics with object-oriented principle. So, it is fundamental to propose metrics for control the quality of this kind of databases. But metrics definition must be done in a methodological way, it is necessary to follow a number of steps for ens...

An XML Storage System for Object-Oriented/Object-Relational DBMSs

As XML has become popular as a document standard in the World Wide Web, a lot of research has been done on the XML storage systems, which store and manage XML documents using existing DBMSs. Most of the research activities, however, assume a relational DBMS instead of an object-oriented/object-relational (OO/OR) DBMS, which offers more powerful modeling capabilities. In this paper, we present t...
