## What it is
Baum is a PHP library implementing the Nested Set pattern for Laravel's Eloquent ORM, enabling efficient storage and querying of hierarchical tree data. It handles the complex SQL for insertions, moves, and deletions behind the scenes, allowing fast non-recursive queries on ordered trees.

## Use cases
- store hierarchical categories in Laravel with fast descendant queries
- build ordered menu trees with Eloquent models
- manage threaded comments or forum posts efficiently
- query all descendants of a node in a single SQL query
- implement nested set tree structures in a Laravel app

## When to choose
- you use Laravel's Eloquent and need ordered tree data with fast reads
- your trees are large and queried frequently, e.g. menus or category trees
- you want insert/move/delete complexity handled for you

## When to avoid
- you are not using Laravel or Eloquent
- your data is write-heavy with frequent tree restructuring
- you only need simple parent-child relations without ordered traversal

## Facets
- artifact type: library
- maturity: maintenance
- function: orm, database
- domain: web-development, databases, developer-tools
- platform: php
- tags: laravel, eloquent, nested-set, hierarchical-data, tree-structure, web-server
