Relationship Design Using Spreadsheet Reasoning for Sets of Functional Dependencies

  • Conference paper
Advances in Databases and Information Systems (ADBIS 2006)

Part of the book series: Lecture Notes in Computer Science ((LNISA,volume 4152))

Abstract

Entity-Relationship and other common database modeling tools have restricted capabilities for designing a relationship of higher arity. Although a complete and unambiguous specification can be achieved by traditional functional dependencies for relational schemata, use of the traditional formal notation in practice is rare. We propose an alternative way: designing or surveying the properties of a non-binary relationship among object classes or attributes is considered by spreadsheet reasoning methods for functional dependencies. Another representation by the semilattice of closed attribute sets can also be used in parallel due to convenient conversion facilities.

This work was supported by the Hungarian National Office for Research and Technology under grant RET14/2005 and the German Academic Exchange Service (DAAD) research scholarship A/05/10580 in cooperation with the MÖB (Hungarian Scholarship Committee).
