Abstract
This paper aims to provide limited knowledge awareness to a conventional DBMS (Database Management Systems). This goal is achieved by extending an off-the-shelf DBMS (Postgresql in our case) in such way that it becomes ontology aware. The concept of ontology is used in our approach as a way of formalizing knowledge and relationships among objects in a domain of interest. Our solution is compounded by two main pieces: an external knowledge server and a set of functions to extend the DBMS. We argue that our solution is both powerful in the sense of supporting knowledge retrieval in the queries, and generic, in the sense that it can be deployed in any DBMS with the support for user-defined functions. Two application domains that can benefit from our approach are data mining and ad hoc query processing in hypothesis exploration environments (e.g. medical research). We also argue that our approach is original in how it pushes a conventional DBMS towards having features like the ones expecte...
