This week's book giveaway is in the OCAJP forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide 1Z0-808 and have Jeanne Boyarsky & Scott Selikoff on-line! See this thread for details.
Hi hyiner, Welcome to JavaRanch, the absolute best site on the www for Java information. We don't have many rules around here, but we do have one. Please change your display name to a first and last name to comply with the JavaRanch Naming Policy. You can change it here. Thank you for your cooperation. Well maybe the best place to start is at the official JDO web page. A search of Amazon only revealed one book by Wrox which appears to only briefly discuss JDO. You can also do a search here at JavaRanch in the JDBC forum.
Any intelligent fool can make things bigger, more complex, and more violent. It takes a touch of genius - and a lot of courage - to move in the opposite direction. - Ernst F. Schumacher
O'Reilly has a new book on the very subject: Java Data Objects by David Jordan and Craig Russell. ISBN: 0-596-00276-9
APress has one also, called Using and Understanding Java Data Objects By David Ezzio ISBN: 1-59059-043-0 Haven't checked them out, yet, but I plan to check them both out at some point. Hope this helps.
