Composable Schema Mappings for Data Integration
Under what assumptions can source-to-domain and domain-to-consumer mappings replace pairwise integration logic?
Question and scope
a conditional \(N+M\) reuse result with domain maintenance, exceptions, partiality, ambiguity, and loss made explicit.
Research artifacts
composition model, normalization examples, identity boundary, integration case study, and repair-surface measurement.
Evidence and evaluation
composed-result equivalence and controlled source/consumer evolution study.
Claim boundary
every ETL workload disappears or data never moves.
