Apache OpenJPA is the Java persistence project of the Apache Software Foundation. After quite some time flying under the radar, there's a new release. Let's look into it. JPA, aka the Java Persistence API, manages persistence and object relational mapping in Java EE and Java SE environments. Libraries like OpenJPA, Hibernate or EclipseLink are those providing the implementations of the standard. By writing code that adheres to the API you are not constrained by the specific library's features, despite the fact that sometimes the additional non-standard functionalities they provide can be desirable. Therefore you are free at any time to swap those libraries behind the scenes for improved performance, reduction in bug count or edge cases. full article on i-programmer: https://www.i-programmer.info/news/80-java/15450-apache-openjpa-life-beyond-hibernate.html
