DataLineageMap: SQL Query Dependency Tracker
Visual dependency mapper that shows exactly which dashboards, reports, and data products break when a single database column is deleted or renamed, built for data teams at mid-market companies.
The Problem
When data engineers modify schemas or drop columns, they have no way to know which downstream dashboards, BI reports, or ML pipelines will break until users complain. Most companies manually track these relationships in spreadsheets or Notion docs that go stale immediately.
Target Audience
Data engineers and analytics engineers at companies with 50-500 employees who use Postgres, Snowflake, or BigQuery and have 20+ interconnected dashboards/reports but no enterprise data governance tool.
Why Now?
AI-powered code analysis (Claude) makes it trivial to extract dependencies from SQL queries at scale; 5 years ago this needed manual parsing. Remote work culture means fewer institutional knowledge keepers who remember which dashboards depend on which columns.
What's Missing
Existing solutions are enterprise-grade and priced accordingly; there's no $99/month option that just maps dependencies without requiring months of onboarding or metadata management.
