Data Warehouse Development in Derry
Bringing a Derry organisation's data into one modelled place so reporting stops depending on exports. A warehouse is worth building when several questions need combined data regularly — building one before knowing the questions is the most reliable way to spend a large budget on something nobody uses.
Why this comes up
The problem
Reporting means exporting from three systems and joining them in Excel. It takes a day each month, only one person can do it, and any question outside the usual report means starting again.
What you get
What we deliver
- The questions and decisions established first, so the model has a purpose
- Loading from your source systems on a schedule, replacing manual exports
- A modelled layer with agreed definitions, not raw tables copied across
- Incremental loading, since full reloads stop scaling sooner than expected
- Historical change tracked where you need to report on how things were
- Documented lineage, so a number can be traced back to its source

Data Warehouse Development in Derry — common questions
- Do we need a warehouse?
- If reporting regularly needs data from several systems joined, yes. If one system holds nearly everything, reporting against it directly is cheaper and simpler. The manual-export monthly cycle is the clearest signal that the threshold has been crossed.
- Which platform?
- BigQuery, Snowflake or a well-configured PostgreSQL all work; the choice follows your cloud, your volume and your team's skills. Platform matters far less than modelling — a badly modelled Snowflake warehouse is worse than a well-modelled Postgres one.
- How long does it take?
- A first useful subject area is usually weeks, not months, if scoped to specific questions. Projects that promise the whole organisation's data at once run long and often deliver nothing usable until very late, which is when enthusiasm has already gone.
- Do we need to keep history?
- If you ever report on how something was at the time — which supplier a product had last year, which team a person was in — then yes, and it must be designed in. Retrofitting historical tracking onto a model that only holds current state is a rebuild.
- Do you work with businesses across County Londonderry?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Northern Ireland, including Derry and the surrounding County Londonderry area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Derry businesses do you usually work with?
- Cross-border trading systems for businesses working into Donegal, and manufacturing tooling for the north west. Beyond that we work across Manufacturing, Healthcare, Higher Education, Digital and Tourism.
- Do you cover the areas around Derry?
- Yes — we work throughout Northern Ireland, including Belfast, Lisburn. Derry is an urban area of roughly 85,000+, and we take on work across the wider County Londonderry region rather than the city boundary alone.
