ExpreSQL

ExpreSQL is a fork of Oracle Quick SQL, a tool that translates an indentation-based shorthand syntax (QSQL) into relational DDL, ERD metadata, and PL/SQL scaffolding.

The v2.0.0 rewrite introduces a multi-dialect architecture in TypeScript, replacing the original monolithic JavaScript codebase.
