Stop hand-building a galaxy of star schemas. If the business layer is modeled, the consumption layer - Unified Star Schema, mart, OBT, star - is downstream of it and should generate itself.
Analytical systems are built for questions that do not exist yet. A layered DAS/DAB/DAR architecture with ensemble modeling makes continuous change survivable.
