AbstractThis paper describes a framework that supports the simultaneous evolution of objectoriented
data models and relational schemas with respect to a tool-supported object-relational
mapping. Thereby the proposed framework accounts for non-trivial data migration induced by
type evolution from the outset. The support for data migration is offered on the level of transparent
data access. The framework consists of the following integrated parts: an automatic
model change detection mechanism, a generator for schema evolution code and a generator
for data migration APIs. The framework has been concepted in the IMIS project. IMIS is
an information system for environmental radioactivity measurements. Though the indicated
domain especially demands a solution like the one discussed in the paper, the achievements
are of general purpose for multi-tier system architectures with object-relational mapping.
