Abstract
Selection conditions for conventional database-query languages are not natural enough to express criteria with fuzzy concepts. To choose some alternatives from a database requires the techniques of multicriteria decision making or conflict resolution. However, some traditional techniques in this area still have some drawbacks, such as inefficiency and independency of criteria. In this paper a fuzzy database-query language is presented and its position in the area of multicriteria decisions making in database applications is discussed and identified. The selection constraints of this query language can accept both crispy and fuzzy conditions. © 1990.
