Data Warehouse Migration for Healthcare & Hospitals

SQL dialects differ in ways that quietly change results, especially around nulls, dates and rounding. We document every behavioural difference rather than assuming equivalence.

In healthcare & hospitals, clinical safety and patient privacy mean nothing ships without human oversight and a complete audit trail. That single fact reshapes how data warehouse migration has to be built here, the guardrails, the approval points and the evidence trail are design inputs rather than things bolted on before go-live.

The workload we are most often asked to take on first is prior authorisation and insurance paperwork, usually integrated against HIS / HMIS. We build the smallest thing that proves the case, put it in front of real users, and expand only what earns its keep.

Built by engineers who ship production systems, not by a practice that subcontracts the build. We hand over with runbooks, tests and a team that knows how it works, not a dependency.
