Editado por Décio Fonseca. aThe mapping of ER schemas containing complex specialization structures into the relational model requires the use of specific strategies to avoid inconsistent states in the final relational database. In this paper, we generalize a proposed strategy for mapping such structures and caracterize the class of ER schemas for which it generates relational schemas that correctly captures their semantics. We also show that this strategy may be adapted for generating optimized relational schemas for which the number of inclusion dependencies to be enforced is reduced.1 aLAENDER, A. H. F.1 aCASANOVA, M.
