The Prometheus database for taxonomy

This paper presents the work carried out in the Prometheus project and its motivation, taxonomy. Taxonomy presents challenges to common database systems. Because of its complexity and the necessary treatments applied to its data, common database model such as the relational, the object-oriented of even graph models are not able to support taxonomic applications fully. Our approach is the extension of a object-oriented database model with explicit relationships in order to support new features and thereby offer the necessary level of service for developing taxonomic applications
