A Language for Fuzzy Statistical Database

摘要

Fuzzy statistical database is a database used for fuzzy statistical analysis purpose. A fuzzy statistical table is a tabular representation of fuzzy statistics and is a useful data structure for fuzzy statistical database. Primitive fuzzy statistical tables are a building block of fuzzy statistical table. In this paper we defined the fuzzy statistical join operator in the framework of fuzzy statistical database. The fuzzy statistical dependency preservation property will be discussed for the fuzzy statistical join. We also propose a set of fuzzy statistical table manipulation operators for arbitrary fuzzy statistical tables and discuss an implementation for them. These findings offer important insights into the retrievability of information from a fuzzy statistical database.
