How Banks Unify Customer Data Across Silos
Connect core banking, CRM, LOS, card processors, mobile apps, call center, and martech into a governed identity graph and golden customer profile that powers compliant personalization and revenue reporting.
Direct Answer
Banks unify data by building a governed identity layer that resolves individuals and households across systems, then standardize events with a shared taxonomy and route into a golden profile (CDP/MDM). ELT pipelines, server-side tagging, and consent management feed analytics and activation—so offers, service, and attribution use the same truth.
What Changes Inside Data Unification
Bank Data Unification Playbook
Make the golden record usable—from collection to activation to revenue measurement.
Discover → Model → Resolve → Ingest → Govern → Activate → Measure
- Discover sources: Core, CRM, LOS, card, call center, web/app, partners; map IDs and data quality.
- Model the profile: Define customer/household schema, consent fields, lifecycle stages, and SOR rules.
- Resolve identity: Create rules for match/merge, survivorship, and household relationships.
- Ingest & transform: Build ELT/CDC pipelines with validation, lineage, and error queues.
- Govern access: Role-based policies, purpose filters, and retention + DSR workflows.
- Activate segments: Share governed audiences to MAP/ads/contact center and capture responses.
- Measure revenue: Consent-aware attribution from lead→approval→funding→activation→LTV.

| Golden Profile | MDM/CDP | Conflicting fields | Survivorship rules, lineage, versioned attributes | Merge Accuracy, Profile Completeness |
| Event Taxonomy | Analytics | Channel-specific names | Standard events for lead/app/approval/funding/activation | Attribution Coverage |
| Consent & Policy | Compliance + MOPS | Manual checks | Purpose filters & retention enforced in queries/activations | Opt-out SLA, Policy Violations |
| Activation & Feedback | MOPS | One-way exports | Bidirectional sync with response capture | Time-to-Segment, ROMI |
