JPA专业知识可以转让给Toplink吗？

Question

JPA和Toplink有何相似之处，使得其中一个方面的专业知识可以延续到另一个领域？

Answer 1

JPA is a subset of the features offered by TopLink. If you feel your needs are met by JPA, then use that. It will give you a simple route should you need to change ORM solution later.

Answer 2

As I understand it, TopLink is an implementation of the JPA standard. There are others as well, and using TopLink implies using JPA. Of course with the newer versions of the JPA standard, I would suggest using a more robust architecture such as Hibernate. The JPA standard infact borrowed quite a bit from Hibernate, and so now they are inline with one another. Another advantage is that there is a lot of reference material online for Hibernate, and TopLink is nowhere close to this.

Hibernate is a pretty complex tool, but experience in it would be highly desirable in any Java shop.
