DEPENDENCES ATTRIBUTES OF INFORMATION SYSTEMS AND PROPERTIES OF UPPER APPROXIMATION BASED CLOSE FUNCCTION.
Abstract
This paper investigates some properties of dependence attributes in information systems. In the paper we have been proposed a closed mapping and consequently we have showed some properties and formulas of upper approximation.
Furthermore, it has been shown that single information system and set-value information system determine each other.
