DatalineageMap: SQL Query Dependency Visualizer
Automatically maps data lineage and dependencies across SQL queries, tables, and dashboards to show exactly where each metric comes from.
The Problem
Data teams spend hours manually tracing where metrics originate when dashboards break or results don't match. There's no easy way to see which queries feed which tables, which dashboards depend on which tables, or which upstream changes will break downstream reports—forcing analysts to either maintain fragile spreadsheets or dig through version control.
Target Audience
Data analysts and BI engineers at mid-market companies (50-500 employees) using SQL databases (Postgres, MySQL, Snowflake, BigQuery) who maintain 10+ dashboards and need to understand metric dependencies.
Why Now?
Post-pandemic remote work has made documentation critical, and AI tools make SQL parsing/analysis much faster to implement; data stack fragmentation means more dependencies to track.
What's Missing
Existing tools are either enterprise-only (expensive) or focused on data quality, not dependency visualization; SQL parsing libraries are now mature enough for a vibe coder to build this in 4-6 weeks.
