Ebean is fast and simple data access on the JVM.  With Ebean it is very easy to insert, update, delete. There is no Session or EntityManager to manage, no merge/flush/attach/detach semantics.  Ebean can profile the object graph use and use that to automatically optimise ORM queries such that they only fetch the required properties and minimises N + 1.

Its features include  JPA Mapping annotations, Type safe queries, ElasticSearch integration and lot more.

Ebean - ORM for Java / Kotlin

Apache OpenJPA is a Java persistence project at The Apache Software Foundation that can be used as a stand-alone POJO persistence layer or integrated into any Java EE compliant container and many other lightweight frameworks, such as Tomcat and Spring. 

Apache OpenJPA - Java Persistence API Implementation

FluentJPA is a Language Integrated Query (LINQ) technology for relational (SQL) databases and JPA. It allows you to use Java to write strongly typed queries by directly integrating into the language. At first glance, it seems that we need a hook in the Java compiler. But in fact, we have full access to the compiled bytecode, which has all the necessary "knowledge". This is how FluentJPA does its magic - it reads the bytecode and translates it to SQL.

Fluent API - LINQ to SQL for JPA

The Dali Java Persistence Tools Project, a sub-project of the Web Tools Platform Project , provides extensible frameworks and tools for the definition and editing of Object-Relational (O/R) mappings for Java Persistence API (JPA) entities. JPA mapping support focuses on minimizing the complexity of mapping by providing entity generation wizards, design-time validation, and a rich UI for entity and persistence unit configuration. 

Dali - Java Persistence Tools from Eclipse

A JPA 2.0 compliant Object-Datastore Mapping Library for NoSQL Datastores. The idea behind Kundera is to make working with NoSQL Databases drop-dead simple and fun. Currently it supports Cassandra, MongoDB, HBase and   Relational databases.


Kundera - JPA 1.0 ORM library for the Cassandra/Hbase/MongoDB database.

jOOQ stands for Java Object Oriented Querying, it  effectively combines complex SQL, typesafety, source code generation, active records, stored procedures, advanced data types, and Java in a fluent, intuitive DSL. It is NOT an OR-mapper, but provides a 1:1 mapping between tables/views and classes. Between columns and members. It supports all standard SQL language features including the more complex UNION's, nested SELECTs, joins, aliasing.
