But the analytical system slowly becomes fragile. The challenge is not building a data model once. It’s owning it as a long term system . Why owning the data is important The data model sits at the centre of analytics. It shapes: how metrics are calculated how filters behave how new data sources are integrated how easily others can build on existing work Without ownership, models grow reactively. Short term fixes accumulate into long term complexity, and analysts compensate with increasingly complex logic downstream. Owning the data model introduces intent, continuity, and accountability into analytics. Advanced technical thinking: the data model as infrast...
