OntoDB: An Efficient Solution for Ontology - Based Database Applications

1. Introduction

In the field of data - intensive applications, efficiently managing and querying ontology - based data is crucial. When using unary and binary representations, the cost of updating the database schema needs to be compared with the cost of clustering data in vertical table and hybrid approaches. Many popular OBDB management systems use binary representation to store ontology instances. However, as the number of properties per instance grows, querying becomes more difficult due to the large number of joins required.

2. Context of the Study

• PLIB Ontology Model : In the 90s, the PLIB ontology model was developed for the technical d
