Canonical Lending Data Model

A shared data model that gives business, finance, and technology teams one reliable interpretation of lifecycle events and balances.

A shared model reduces interpretation risk before it becomes a control issue

When each system names, calculates, or stages data differently, reporting disputes multiply and downstream controls weaken.

The Canonical Lending Data Model standardizes entities, lifecycle states, and event meanings so policy, servicing, recovery, and reporting stay aligned.

Table of Contents

Architectural principles

  • Separation of policy, execution, accounting, and AI signal layers
  • Canonical data normalization across lifecycle stages
  • Event-driven state transitions with audit traceability
  • Versioned APIs and controlled change governance
  • Hybrid-ready deployment topology

System boundaries

  • LL governs: workflows, policies, accounting events, audit evidence
  • Enterprise retains: core ledger and ERP authority
  • Integration layer: REST, OAuth2/OIDC, mTLS, versioning

Data model usage

Why it matters

  • Clarifies platform boundaries for architecture, procurement, and governance review
  • Connects policy, execution, and accounting evidence across related pages
  • Helps executives and implementation teams navigate the operating model with less friction
