Paper Abstract:
|
A fuzzy database has two main features: flexible querying and representation of imprecision or vagueness. The first feature allows querying in linguistic terms.(i.e. selections in terms of age labels like 'young' or 'middle-aged' customers). The representation of vagueness is done by means of possibility distributions and fuzzy constants like 'UNKNOWN' or 'UNDEFINED'. Some comparison operators are usually defined in order to get a similarity degree between fuzzy values. The current paper is based on the ability of an open source framework called Hibernate to isolate the applications from the database implementation. Thus, the present implementation of fuzzy types and flexible querying within Hibernate extends any relational database into a fuzzy database. |
