Mapping a semantic database model to the relational model

Paper Summary

The article explores how to translate complex semantic database models into simpler relational models using the Iris Data Model. The researchers introduced new types of constraints to describe these translations and discovered unexpected information about the Iris schemas. They defined a way to compare different Iris schemas based on their relational translations and found a method to simplify the structure of Iris schemas.
