Some Applications of Fuzzy Databases With FSQL

Abstract

The applications of databases are immense. In almost all of them, the advantages of the fuzzy databases can be applied, exploiting their innovative features and possibilities without losing usefulness. Even the model presented here permits an easy use of those advantages in already existing traditional databases. The Type 1 fuzzy attributes are traditional attributes that admit fuzzy queries on them (by using labels, approximate values, fuzzy comparators, etc.). Imprecise information is a common phenomenon in any context, so it is not unusual to receive information in an incomplete or inexact way. In traditional databases, if information other than precise information exists, the value NULL is stored, preventing the storage of any known information, because the facts are not precise.
