Signature system
One machine, from 128 ledgers to a board decision.
The systems in these case studies share one architecture. Trace it: select a stage to see what happens there. Every figure is from the case-study record.
Sources Three generations of ERP API — legacy Web Services, OData v2, and an Advanced Analytics beta — across 128 operating companies, each with its own quirks and schema drift.
Router A single router resolves company, source system, and entity type from configuration. New companies are added as metadata, not code; an API change is absorbed in one place.
Model A conformed star schema where measures resolve consistently across entity, currency, scenario, and period — with a Benford leading-digit control watching the ledger fact.
Decisions Group reporting, board-ready decision packs, and M&A analysis all read from the same governed model — one version of the truth, three ways to act on it.
