 4.  **Compilation (Output):** The **Driver** translates the optimized AST into the native dialect (e.g., PL/SQL) of the target database.

 :::info Implementation Note
 While `steedos-server` is the reference implementation (Node.js), the ObjectQL Specification is language-independent. A compliant driver could be written in Go, Rust, or Java.
