Databases that are currently being developed for repositories of digital linguistic information typically fall into the strictly relational category. We present work on an object-relational database which allows for the representation of hierarchical relationships. This has particular benefits for the storage and access of morphological data in the system of word formation. A model that makes use of inheritance hierarchies elegantly captures the relationship between a root, its derivative, and its derivative, and so on. We report on the experimental Node DataBlade, a software bundle that extends the functionality of the object-relational database system Informix (Brown 2001) by supporting the storage and manipulation of hierarchical data. We show how this functionality provides a way of capturing specifically inheritance relationships between members of a derivational family in Russian.
