Motohide Umano, T. Imada, Itsuo Hatono, Hiroyuki Tamura · 2002
Ordinary object-oriented databases have been well studied. We have already proposed a fuzzy object-oriented database that can treat fuzzy-set attribute values with certainty factors and fuzzy inheritance. In this paper, we design and implement an SQL-type data manipulation language and demonstrate its facilities using several examples.
