Recently there has been increasing interest in both the problems and the potential of
accommodating evolving schema in databases, especially in systems which necessitate a
high volume of structural changes or where structural change is difficult. This paper
presents a taxonomy of changes applicable to the Entity-Relationship Model together with
their effects on the underlying relational model expressed in terms of a second taxonomy
relevant to the relational model.
