Java Distributed Objects

Java Data Objects is a standardized Java API for object persistence. It facilitates the storage and retrieval of complex object models with various storage mechanisms, including both object and relational databases. This book is suitable for final year undergraduate students on courses that address Java in database applications. Prior knowledge of JDBC and J2EE is not specifically required, but would help to accelerate the student's understanding of JDO's relationships with these technologies....

Like the servlet and EJB specification, JDO is a standard that is implemented by competing software vendors. Several JDO implementations are currently available as third party products for relational databases and object-oriented databases, and this is a comprehensive guide to its applications.This is an application programmer's guide to the Java Data Objects (JDO) specification recently accepted by the Java Community Process....

Java Data Objects revolutionizes the way Java developers interact with databases and other datastores. JDO allows you to store and retrieve objects in a way that's natural to Java programmers. Instead of working with JDBC or EJB's container-managed persistence, you work directly with your Java objects. You don't have to copy data to and from database tables or issue SELECTs to perform queries: your JDO implementation takes care of persistence behind-the-scenes, and you make queries based on the fields of your Java objects, using normal Java syntax. The result is software that is truly object-oriented: not code that is partially object-oriented, with a large database-shaped lump on the back end. JDO lets you save plain, ordinary Java objects, and does...
