Implementation of the Prometheus Taxonomic Model: a comparison of database models and query languages and an introduction to the Prometheus Object-Oriented Model.

  Types of databases commonly used for handling taxonomic data are compared. It is shown that none of the
existing types of databases fully support the requirements of taxonomic data. The results of this comparison
provide a rationale for the design and implementation of a new database system based on an Extended Object-
Oriented model. The new model, the Prometheus Object-Oriented Model (POOM) and its query language
Prometheus Object-Oriented Language (POOL), are discussed in relation to the requirements of taxonomic
data and the Prometheus Taxonomic Data Model. POOM provides the ability to represent the semantics of
relationships between data. This allows us to build the type of graph structures that are found in taxonomic
hierarchies. In addition, the system can query and manipulate these graphs (POOL). These features have been
used to improve the original Prometheus Taxonomic Data Model. These improvements and the advantages they
offer are described and discussed.
