Free lineage map

Map your own tables and columns, right now

Paste the SQL that builds your models, a dbt manifest.json, or a JSON table list. Datatrail reads the definitions and returns your real map: which table feeds which, which column comes from which column, and what it could not resolve. No card, no warehouse connection, no rows read.

Your SQL, dbt manifest.json, or JSON table list CREATE TABLE stg_orders AS SELECT id AS order_id, customer_id, total_cents, created_at FROM raw_orders; CREATE TABLE stg_payments AS SELECT order_id, amount_cents AS paid_cents, status FROM raw_payments; CREATE TABLE fct_orders AS SELECT o.order_id, o.customer_id, o.total_cents AS gross_cents, p.paid_cents, o.created_at FROM stg_orders o LEFT JOIN stg_payments p ON p.order_id = o.order_id; CREATE TABLE fct_revenue_daily AS SELECT created_at AS day, SUM(gross_cents) AS revenue_cents FROM fct_orders GROUP BY created_at; CREATE VIEW exec_revenue AS SELECT day, revenue_cents AS mrr_cents FROM fct_revenue_daily;

Example SQL is filled in so you can see the shape. Replace it with yours.

Read-only by design. Datatrail reads table and column definitions to build the map and never asks for warehouse credentials or reads a single row. Already registered? Sign in.
