Data Architecture Documentation

The HiAtoms Code & Database Architecture Engine is a local-first AST parser. It reads your raw DDL or Prisma files and automatically constructs a rigorous Entity-Relationship mapping without requiring a live database connection.

Frequently Asked Questions

What formats are supported?

The parser currently supports basic standard SQL DDL (`CREATE TABLE` statements), Prisma schema files (`model {}` blocks), and raw JSON arrays (where it infers the schema from the first object's keys).

Does this send my schema to a server?

No. The entire abstract syntax tree (AST) parsing and architecture generation happens directly in your browser. No schema data is transmitted or logged.

Can I export the generated ER diagram?

Yes. The generated mermaid diagram syntax can be copied directly and embedded into GitHub READMEs, Notion pages, or internal documentation wikis.
