Getting your data in order
From loose exports to one version of the truth: master data, one source per field, pipelines, warehouse and migration, and why this decides whether AI works.
After this series you can:
- You point out where your data drifts apart and count how big the problem is, before you build.
- You record per piece of data which system is the source, who decides, and what is checked at entry.
- You pick what your data question needs: a pipeline, a warehouse or a migration, and require every step checked.
