Enterprise Reference Data Platform

01 Overview

Overview

A governed reference-data platform so downstream systems share consistent identifiers, hierarchies, and change history.

02 Business / Engineering Context

Business / Engineering Context

Shared identifiers and hierarchies were required by multiple downstream systems that had drifted into local copies.

03 Problem

Problem

Inconsistent reference data across systems created reconciliation cost, broken joins, and slow change.

04 Constraints

Constraints

• Consumers needed a stable contract while the source of record was being established
• Write access could not be implied by the need to read reference data

05 Architecture

Architecture

• Authoritative store for shared reference entities
• Distribution through APIs and events rather than ad-hoc files
• Versioned change so consumers could reason about what moved
• Clear ownership of data stewardship versus consumption

08 Security

Security

Reference data publication was controlled; not every consumer needed write access.

10 Observability

Observability

Change publication and consumer lag needed to be visible so stale data did not silently spread.

12 Outcomes

Outcomes

• A production reference-data platform used as a shared source for downstream systems
• Reduced ambiguity in identifiers and hierarchies across consuming applications
