The JDO 1.0 standard was release in March 2002. The 1.0.1 maintenance update (scheduled during the first half of 2003) contains a number of minor corrections, clarifications and feature enhancements that have been included in this book. During 2003, work should commence on the JDO 2.0 specification with a scheduled release of sometime in 2004.

JDO 2.0 will focus on adding commonly requested features and functionality to JDO, and this chapter highlights some of those possible features. The features covered in this chapter are in no way guaranteed to make it into JDO 2.0, nor do they represent the limit of new features that may be considered . Rather, this chapter aims to give some insight into what may be in store in future revisions of the JDO specification.

This chapter covers the following topics:

• Advanced transactions semantics

• Performance optimizations

• Managed relationships

• Query enhancements

• Object mapping

• Enumeration pattern
