# recursive-doc-model

Explores using a relational model to express a recursive document model where

one document (origin) can reference another (destination). Destination documents

can also contain references.

The first question explored here is how can we collect a specific attriibute,

in this case _ingredients_, for all documents referenced by the origin document

(either directly or indirectly).

## Try it yourself

Depends on:

  1. psql

  1. docker compose (built in to newer Docker cli versions)

### Commands

```bash

  # Start

  make

  # Stop

  make clean

  # Example query

  psql "postgres://admin:test123@localhost:5432" -f sql/query.sql

```
