Reasoning Methods for Designing and Surveying Relationships Described by Sets of Functional Constraints
This work is supported by the Hungarian Scientific Research Fund (OTKA), grant T042706. Current methods of database schema design are usually based on modeling the real world as entity (or object) classes with relationships among them. Properties of relationships can be described by semantical database constraints. One of them is functional dependency, which has a key role in traditional database design. The three basic types of binary relationships that can be described by functional...
