Data Architecture Design
CRM & Data / Data Architecture Design

The data model that makes everything else work

Entity relationship design, field hierarchy, ownership rules, and integration topology -- all designed before a single field is configured. The work most agencies skip.

Why Data Architecture Design projects fail

01

Fields added without a model

Admins add fields reactively to solve immediate problems. 2 years later there are 400 fields, 60% unused, and nobody knows what anything means.

02

No single source of truth

Account, Contact, and Lead objects all store conflicting versions of the same customer. Reports require manual reconciliation every time.

03

Scaling breaks the configuration

What works for 50 users fails at 500. Object relationships, sharing rules, and automation logic need to be redesigned from scratch.

04

Integration topology not planned

Every new integration is bolted on separately. No common data layer. Middleware becomes spaghetti. Changes to one system break three others.

The architecture Celumai designed has scaled from 200 to 2,000 users without a single structural change. That is what good data modelling looks like.

Enterprise BFSI Group

Three previous consultants had built on top of each other without a coherent model. Celumai redesigned the entire architecture in 3 weeks and the difference was immediate.
