Chapter 12. JDO implementations

Our examination of JDO 1.0 is now complete. This penultimate chapter gives the reader an introduction to some of the most important JDO Implementations and the companies behind them.

For each vendor there is a page or two about the company, their products, and the extent of their support for various data stores and application servers. Some of the products listed are object-relational mapping implementations which work with an underlying relational database. Others are themselves fully fledged object databases for which a JDO interface is provided.
