Data Warehousing
A modelled, governed warehouse that becomes the single place people go for numbers.
A warehouse becomes the single source of truth only when people prefer it to their spreadsheet. That depends far more on modelling and documentation than on which platform you bought.
We build modelled, governed warehouses — conformed dimensions, agreed grain, documented lineage — that become the place people actually go for numbers.
How we approach it
We model deliberately rather than copying source tables across. A warehouse that mirrors your operational schema inherits every one of its quirks.
Why this matters
-
One place for numbers
A modelled layer that answers questions across systems.
-
Consistent definitions
Conformed dimensions so departments compare like with like.
-
Governed access
Row and column-level security appropriate to each audience.
-
Cost controlled
Storage and compute designed and monitored for predictable spend.
What is included
-
Dimensional modelling
Facts and conformed dimensions at an agreed, documented grain.
-
Historical tracking
Slowly changing dimensions so history is preserved correctly.
-
Access governance
Role-based access with masking for sensitive attributes.
-
Cost monitoring
Query and storage cost attribution with alerting.
How we deliver it
-
01
Discover
Workshops with the people who will use it, a map of the systems the warehouse has to fit alongside, and written agreement on what success looks like.
-
02
Design
Architecture, data model and interface prototypes, reviewed with your team before any production code is written.
-
03
Build
Two-week increments with a demo environment you can use throughout, so the roadmap stays open to change.
-
04
Harden
Load testing, security review, accessibility audit and the operational tooling needed to go live safely.
-
05
Operate
Support, iteration and a documented handover whenever you decide to run it in-house.
What you receive
- Dimensional model and documented grain
- Production warehouse with governed access
- Historical tracking implementation
- Cost monitoring and optimisation report
- Documentation and analyst training
What clients say about this work
“The warehouse they built is the first one our clinicians trust. That is entirely down to how much time Vertexa spent on data quality before building a single dashboard.”
