Bacterial Virus Ontology; Coordinating across Databases

Bacterial Virus Ontology; Coordinating across Databases

Bacterial viruses, also called bacteriophages, display a great genetic diversity and utilize unique processes for infecting and reproducing within a host cell. All these processes were investigated and indexed in the ViralZone knowledge base. To facilitate standardizing data, a simple ontology of viral life-cycle terms was developed to provide a common vocabulary for annotating data sets. New t...

Coordinating Mobile Databases

We are interested in the development of a database management layer which is completely portable and, therefore, “pluggable” on top of multiple host platforms. This layer, so called Peer Database Management System (PDBMS), must be able to remotely connect with its database and to connect it with other peer databases. We realize mobility by storing PDBMS on a flash drive. We realize network inde...

Coordinating Peer Databases Using ECA Rules

Peer databases are stand-alone, independently developed databases that are linked to each other through acquaintances. They each contain local data, a set of mapping tables and expressions, and a set of ECA rules that are used to exchange data among them. The set of acquaintances and peers constitutes a dynamic peer-to-peer network in which acquaintances are continuously established and abolish...

Coordinating Mobile Databases: A System Demonstration

Ontology-based Relational Databases

There remain important gaps, both structurally and semantically, between the conceptual design of a database and its implementation in relational database management systems (RDBMS). To fully realize the idea of data independence that has made databases so popular for application programmers, we should try to bridge this gap. This study explores the use of ontologies, which have become a popula...
