 GraphQL JPA Query library uses JPA 2.1 specification to derive and build GraphQL Apis using GraphQL Java for your JPA Entity Java Classes. It provides a powerfull JPA Query Schema Builder to generate GraphQL Schema using JPA EntityManager Api and instruments GraphQL Schema with JPA Query Data Fetchers that transform GraphQL queries into JPA queries on the fly.
 
-GraphQL is a query language for Web APIs implemented by GraphQL Java [graphql-java 11.0](https://github.com/andimarek/graphql-java) runtime for fulfilling those queries with your existing data. GraphQL provides a complete and understandable description of the data in your API, gives clients the power to ask for exactly what they need and nothing more, makes it easier to evolve APIs over time, and enables powerful developer tools.

 Your applications can now use GraphQL queries that smoothly follow references between JPA entities with flexible type safe criteria expressions and user-friendly SQL query syntax semantics i.e. query by page, where criteria expressions, select, order by etc.

 GraphQL JPA Query creates a uniform query API for your applications without being limited by a single data source. You can use it with multiple JPA compliant databases by instrumenting a separate EntityManager for each DataSource and expose a single GraphQL Query Apis for your Web application domain using Spring Boot Auto Configuration magic.
