EclipseLink

EclipseLink is a cool, free tool that helps Java developers work with all sorts of data services. Whether it's databases or different kinds of information systems, this software makes it easier to manage everything. Plus, it supports Object XML mapping (OXM) and even web services for XML and relational databases.

Compatibility with Persistence Standards

This tool is compatible with several important persistence standards like Java Persistence API (JPA), Java Connector Architecture (JCA), Java Architecture for XML Binding (JAXB), and Service Data Objects (SDO). Each of these plays a key role in how you manage data within your Java applications.

Understanding JPA

The JPA is an interface that helps manage relational data in Java tools. It includes features like the API, Java Persistence Query Language (JPQL), and object-relational metadata. On the other hand, JCA connects application servers with enterprise information systems for smooth application integration.

Mapping with JAXB

JAXB is another framework integrated into EclipseLink as MOXy. It’s super handy for mapping Java classes to XML representations! And let’s not forget about SDO, which allows you to access different types of data in a consistent way.

Diving into SQL Examples

If you're looking to get started with SQL using EclipseLink, you can check out some basic configuration examples on their download page here!. You’ll find tutorials on how to use EclipseLink JPA in a JSF application or explore various other JPA examples too!

No-SQL Access Made Easy

EclipseLink also offers no-SQL options. You can learn how to access MongoDB through JPA or dive into polyglot persistence, which combines both relational and no-SQL approaches!

Licensing Information

The project operates under two licenses: the Eclipse Public License 1.0 and the Eclipse Distribution License. So, you can feel confident using this powerful tool without any worries!
