Platform Architecture | Canonical Data Model for Senior Housing & Care
The industry has been told for two decades that senior housing & care requires 8–12 systems wired together — an EHR for clinical, a PMS for real estate, a CRM for move-ins, a scheduler for staff, a portal for families, an accounting connector for finance, a BI tool for the board. Each one owns its own truth. Each one charges its own seat. Each one breaks on its own cadence. The reconciliation tax — the 14–22 hours per community per week spent matching numbers between systems — is the silent line item nobody underwrites.
The eight canonical entities
Every module on the platform reads and writes against the same eight records. There is no integration layer between them because there is nothing to integrate.
Why the architecture is the moat
Best-of-breed stacks have a half-life of roughly 18 months — a vendor sunsets, gets acquired, raises pricing, or stops maintaining an integration. Every event triggers a migration the operator did not budget for. A canonical data layer removes that risk surface entirely: the operator owns the schema, the export, and the audit trail . Vendor churn becomes a procurement decision, not an existential one.
Equally important, a canonical model is the only way to deliver outcomes that cross functional lines — cleaner claims, clinician hours returned, occupancy lift, and audit-grade survey readiness — because every one of those outcomes depends on data that lives in multiple legacy systems today. Unify the data and the outcomes follow.
Governance is part of the architecture, not bolted on
multi-layer tenant isolation is enabled on every public table. Access is mediated by server-side access helpers functions tied to the authenticated session and the operator hierarchy. A role enum gates every mutation. Tenant isolation is enforced at the database layer, not the application layer — meaning a bug in application code cannot leak data across operators. The immutable audit log is append-only at the schema level and is the evidence base for state survey and SOC 2 Type II reporting (Type I and Type II in progress).
