The equivalence-preserving transformation and normalization of types in object-oriented databases are discussed. Specifically, a normal form of types based on set-theoretic equivalence is proposed, rewrite rules which transform types into normal forms are presented, and the uniqueness of normal form and the completeness of rewrite rules are proved.
