My work on data lineage
I often need to understand a new technology quickly in order to reconstruct its lineage: BigQuery, Alteryx, SAP, SAP HDI, Oracle ODI, Impala, COBOL and others.
Decode a technology
Identify its objects, execution model and the way it expresses processing logic.
Reconstruct lineage
Connect sources, transformations and outputs, even when dependencies are spread across code and metadata.
Make the analysis reliable
Turn that understanding into verifiable, reusable analysis rules for real programs.
Experience across software, data and languages
Since 2013, my experience has covered systems for analysis, search, risk and software transformation.
How I approach an unfamiliar technology
The starting point is not a list of syntax rules, but an operating model to discover and test.
Start with the real operating model
I examine the artifacts, execution model and metadata that actually determine the data flows.
Separate syntax from semantics
I connect technology-specific constructs to common concepts: reading, transformation, writing and dependency.
Validate the difficult cases
I test the reconstructed lineage against representative programs, then address ambiguities and exceptions.
