## What it is
Elide is a Java library that generates model-driven JSON-API and GraphQL web services from JPA-annotated data models with minimal effort. It provides declarative security permissions, atomic multi-object mutations, filtering/sorting/pagination, and a semantic layer for analytic queries.

## Use cases
- expose JPA entities as a JSON-API or GraphQL CRUD service
- build a GraphQL API from Java data models without writing resolvers
- add declarative field- and entity-level access control to an API
- serve analytic aggregate queries over a semantic model layer
- perform atomic multi-object create/update/delete in one request
- visualize and explore data with Yavin dashboards over Elide APIs

## When to choose
- you have JPA/Hibernate models and want a full CRUD or GraphQL API quickly
- you need fine-grained declarative permissions on API fields and entities
- you want built-in filtering, sorting, pagination, and subscriptions
- you're building analytics/reporting APIs with a semantic layer

## When to avoid
- you're not on the JVM or don't use JPA/Hibernate
- you need full manual control over API endpoints and resolvers
- your data layer isn't relational or JPA-compatible
- you need a lightweight REST framework without model-driven conventions
