Reflections on Boyce-Codd Normal Form

1. Introduction

Finding Faithful Boyce-Codd Normal Form Decompositions

It is well known that faithful (i.e. dependency preserving) decompositions of relational database schemas into Boyce-Codd Normal Form (BCNF) do not always exist, depending on the set of functional dependencies given, and that the corresponding decision problem is NPhard. The only algorithm to guarantee both faithfulness and BCNF (if possible) proposed so far in [Os79] is a brute-force approach ...

Characterizations for Functional Dependency and Boyce-CODD Normal Form Families

A functional dependency (fd) family was recently defined [20] as the set of all instances satisfying some set of functional dependencies. A Royce-Codd normal form, abbreviated RCNF. family is defined here as an fd-family specified by some RCNF set of functi!)nal dependem& . The purpose of this paper is to present set-theoretic/algebraic characterizations relating to both types of families. Two ...
