What is TopLink?
TopLink is an ORM(object relational management) framework for Java. Like the other popular framework Hibernate, using TopLink we can map Java objects to database entities or tables and can do various persistent operations. Also we can convert Java objects into XML objects. It is a product from Oracle Corporation. In 2007, Oracle donated the source code to Eclipse Foundation and the project EclipseLink was born. EclipseLink is the reference implementation for the Java Persistence API (JPA).
