## What it is
Morphia is a Java object-document mapper (ODM) for MongoDB built on top of the official MongoDB Java driver. It maps Java and Kotlin classes to MongoDB documents, providing type-safe persistence and querying.

## Use cases
- map Java POJOs to MongoDB documents
- query MongoDB with type-safe Java APIs
- persist Kotlin objects in MongoDB
- replace raw MongoDB driver boilerplate with an ODM
- manage entity annotations and indexes for MongoDB collections

## When to choose
- you use MongoDB from Java or Kotlin and want ORM-style mapping
- you prefer annotation-based entity mapping over the raw driver
- you want type-safe queries against MongoDB collections

## When to avoid
- you use a relational database instead of MongoDB
- you need Spring Data MongoDB's Spring integration specifically
- you want a driver-free reactive stack with minimal abstraction

## Facets
- artifact type: library
- maturity: active
- function: orm, database-driver, database
- domain: databases, backend, developer-tools
- platform: jvm
- tags: mongodb, odm, object-document-mapper, nosql
