By a decision support system it is meant an expert system that the user can use to inquire about information to make his decision. Such a system will be based on an expert knowledge base. It is believed that the knowledge base is more than facts and rules. It may include less tangible and less codifiable factors like opinions, judgments, educated guesses, as well as factual information and logic rules for reasoning. That is, the knowledge may be explicit, logical, heuristic, or fuzzy. This paper presents some methods to add fuzzy information into a relational data base. Specifically it considers the treatments of fuzzy queries. An answer to a fuzzy query will be a fuzzy set from which a further detailed study can be made. 13 references.
