## What it is
Ohm is a Ruby object-hash mapping (ORM-like) library for Redis, letting you persist and query Ruby objects in a Redis key-value store. It emphasizes simplicity and performance with a lightweight Redis client.

## Use cases
- store Ruby objects in Redis
- use Redis as a persistent database for models
- map hashes to Ruby objects
- build simple data models without a SQL database
- query and index objects stored in Redis

## When to choose
- you use Ruby and want a minimal, fast object mapper for Redis
- your data model fits key-value/hash storage without relational joins
- you want less code and fewer dependencies than a full ORM

## When to avoid
- you need relational features like joins, migrations, or complex transactions
- you need an actively developed library with frequent updates
- your project uses a language other than Ruby

## Facets
- artifact type: library
- maturity: maintenance
- function: orm, database-driver, database
- domain: databases, developer-tools, backend
- platform: ruby
- tags: redis, object-mapping, key-value-store, persistence
