Linaje y Catálogo de Datos

En una frase

Answers "where did this number come from" for any figure in any report, and lists what exists and who owns it.

El problema

When a number in a management report is questioned, tracing it back takes days and frequently ends in a spreadsheet nobody can explain. Data that cannot be traced cannot be trusted, and untrusted data does not get used for decisions.

Cómo funciona

Lineage is captured automatically from pipeline execution rather than documented by hand, so it stays current. A searchable catalogue holds datasets, owners, definitions, quality scores and refresh schedules, and every report figure links back through its transformations to its source records.

Datos necesarios

  • Instrumentation of data pipelines to emit lineage events
  • Dataset ownership assignments from the data governance function
  • Business definitions for key metrics agreed across departments
  • Existing documentation to seed the catalogue

Qué obtiene

  • End-to-end lineage graph from source system to report figure
  • Searchable data catalogue with owners, definitions and quality scores
  • Impact analysis showing what breaks if a source system changes

Qué no puede hacer

Lineage is captured only for data moving through instrumented pipelines. Data that a user exports to a spreadsheet, edits and re-imports leaves the lineage graph and re-enters it as new, and no tooling closes that gap — it is closed by changing the working practice, which is harder.
