In depth

Modern data warehousing: from nightly batch to governed lakehouse

The warehouse is still where the business keeps score. What has changed is the architecture: cloud-native engines, ELT over ETL, and lakehouse patterns that hold raw history alongside conformed marts. We design and migrate warehouses that deliver fast, consistent answers — at a cost finance can live with.

Our builds use Snowflake, Microsoft Fabric, BigQuery, and Redshift, modeled with dimensional and data-vault techniques that survive source-system churn. Migrations from on-prem appliances follow a proven path: inventory, automated conversion where safe, parallel-run validation, and cutover with rollback — reporting continuity guaranteed.

Governance is built in: role-based access, column-level security for PII, and cost controls that stop runaway queries. The result feeds BI and analytics today and ML workloads tomorrow, from one governed foundation.

Modeled to last

Dimensional and vault modeling that absorbs source changes without rework.

Validated migrations

Parallel-run reconciliation proves the new warehouse matches the old — before cutover.

Cost-governed compute

Warehouses sized, monitored, and auto-suspended — no surprise bills.

Frequently asked questions

Have a different question? Talk to an engineer, not a salesperson.

How long does a legacy migration take?

A typical mid-size estate migrates in 6–9 months, phased by subject area so the business never loses reporting.

Kimball or Data Vault?

Depends on volatility and audit needs — we model each subject area pragmatically rather than applying one methodology everywhere.

Will costs drop after migration?

Usually — elastic compute plus tuning cuts total cost for most estates; we baseline before and report the delta.
