We design and build data warehouses for businesses across the UK and Isle of Man. Centralised data platforms that consolidate information from across your organisation into a single, reliable source of truth - making reporting accurate, analytics fast, and business intelligence accessible to the people who need it.
The need for a data warehouse typically emerges when reporting becomes painful. When generating a weekly report requires an analyst to manually extract data from multiple systems and combine it in a spreadsheet. When the same metric shows different numbers depending on which system you query. When your operational database slows down every time someone runs a complex report. These are the symptoms of a business whose data infrastructure has not kept pace with its data needs.
Every data warehouse we design is the work of Owen Jones, OLXR's founder and lead engineer. We treat data warehousing as a serious engineering discipline - not just a place to dump data, but a carefully designed platform that serves your organisation's reporting and analytical needs reliably.

Our Approach
Model the Business, Not the Systems
A data warehouse should reflect how your business thinks about its data - not the structures of the operational systems it draws from. We start by understanding your business domain and the questions your organisation needs to answer, then design a dimensional model that makes those questions easy to answer.
Prioritise Data Quality
A data warehouse that contains bad data is worse than no data warehouse at all. We build data quality validation into the ingestion pipeline - checking for referential integrity, detecting anomalies, flagging records that fail validation. Data that fails validation is not silently loaded - it is surfaced for investigation.
Design for Self-Service
The goal is to make reliable data accessible to non-technical users through BI tools with meaningful names, clear definitions, and pre-calculated metrics. When a warehouse is designed well, business users can answer their own questions without waiting for a developer or analyst to write a query.
