Features: Although the JDO (Java Data Object, Java) standard has a relatively "long" history, during its development process, we could only glimpse a small part of its numerous specifications! The JDO standard originated from the ODMG (Object Data Management Group, ) standard. This standard was among the early attempts to standardize methods for transparent database access in object-oriented programming languages. The ODMG standard appeared even earlier than the Java language itself. This book is suitable for Java application developers with a certain level of Java knowledge, as well as programmers and software architects interested in JDO technology. It serves as a detailed introduction and learning guide to the JDO (Java Data Object, Java) specification and technology. The book consists of 13 chapters, covering the architecture of JDO, object lifecycle states, basic interfaces and classes, transaction management, the JDOQL language, exceptions, integration with J2EE, and knowledge about JDO implementations. The appendix provides useful references such as JDOHelper, PersistenceManagerFactory interfaces, and JDOQL syntax. This book is suitable for Java application developers with a certain level of Java knowledge, as well as programmers and software architects interested in JDO technology.
