What is the Schema Visualizer?
Reading DDL top-to-bottom hides the schema's shape. This visualizer parses CREATE TABLE statements and renders each table as a structured summary — every column with its type, nullability, default, and key flags — plus a relationship index showing which tables reference which, the way data modeling tools display it.
Frequently Asked Questions (FAQ)
Q: Does it support ALTER TABLE statements?
Yes — ALTER TABLE ADD COLUMN and ADD CONSTRAINT are merged into the table's summary.
