Modeling Biometric Systems in UML

In this paper we present an object-relational database for biometric systems and results conducted during implementation. Using a systematization of biometric methods, models and characteristics we developed a UML (Unified Modeling Language) model and ODL (Object Definition Language) specification of the database which can be used for unimodal as well as for multimodal biometric systems. For the implementation we used the objectoriented scripting language Python, and especially the ZODB (Zope Object Database) package for object-base management. In the end we summarize the advantages and disadvantages of such an approach, and give guidelines for future research of such a concept.
