EclipseLink JPA and Oracle NoSQL Database (ONDB)

Back in 2005, I was the Project Lead for JSR220-ORM tooling in Eclipse. Sun’s JSR220 project was the early POJO persistence standard for Java that became the EBJ 3.0 spec, the predecessor of the JPA Interface found today in every Java download.

In the same timeframe, Oracle announced it was joining the Eclipse Foundation and in that process launching a competing JSR220 tooling project called Dali. Needless to say, it did not take long for the JSR220-ORM and Dali project teams to merge into a single project. Eventually, the Oracle team took lead on Dali and marched into the future.

Here I am now 8 years later at Oracle helping drive the standardization of NoSQL technology. JPA presents a great abstraction layer for dealing with database persistence, allowing users of Java to persist their application objects with literally the push of a button.  Plus, when using JPA with a NoSQL database, it allows the developer to use a soft schema approach to application development, where the data model is driven from the application space rather than the database design and evolution of the application can occur much more rapidly.  In fact, in 2005 when I was V.P. Technology for a NoSQL Database company, one of the things we did was create a JPA interface for standards based access to our NoSQL store, the reason we launched that JSR220 tool project in Eclipse. So, I thought I would poke around a little bit with the Oracle NoSQL Database (ONDB) and JPA interfaces. To my surprise, I found that some folks had already made a great start down that path….pretty cool.   There is an EclipseLink plugin that supports NoSQL Databases , including ONDB.
