This invention describes a system that keeps track of how data in individual columns of a database or spreadsheet changes and moves through different processing steps. It does this by creating a visual map, like a family tree, showing which columns depend on others and how they transform. The system then uses this map to generate a graphical interface where users can see these connections, specifically showing related columns on one side of a selected column.
Why it matters: Filed before the widespread adoption of advanced AI for code and data interpretation. Large language models could now significantly simplify the complex task of automatically inferring data transformations and generating the necessary metadata for lineage tracking, making the UI generation more robust.
AI gives you a few directions you could take this. Pick one, and we check whether your version is different enough to patent, then write the filing.
