Abstract :
In order to deal with complex as well as uncertain information, in this paper, we introduce fuzzy data into nested relational database model, where data fuzziness appears in forms of possibility distribution and resemblance relations in the universe of discourse. We present the structure of fuzzy nested relational model and define the algebra for manipulating fuzzy and complex data.
