Fuzzy relational databases have been extensively studied in recent years, resulting in several models and representation techniques, some of which have been implemented as software layers on top of diverse existing database systems. Fuzzy extensions to query languages and end-user query interfaces have also been developed, but the design of programming interfaces has not been properly addressed yet. In this paper, we describe a software framework called fJDBC that extends the Java Database Connectivity API by enabling fuzzy queries on existing relational databases, using externally-stored metadata. Since the main design objective of this extension is usability for existing database programmers, only a restricted subset of extensions (supported also by an extended object modelling notation) has been included. The overall design of the framework and some empirical results are also described.
