Features: This book provides a detailed introduction and learning guide to the JDO (Java Data Objects) specification and technology. It consists of 13 chapters, covering the architecture of JDO, object lifecycle states, basic interfaces and classes, transaction management, JDOQL language, exceptions, integration with J2EE, and knowledge about JDO implementations. The appendix offers useful references such as the JDOHelper and PersistenceManagerFactory interfaces, as well as JDOQL syntax. This book is suitable for Java application developers with basic Java knowledge, as well as program designers and architects interested in JDO technology. It is one of the important translated works in the field of mobile communications, providing a comprehensive and systematic introduction to major wireless communication technologies, data services provided by various mobile communication networks, IP applications, and their development trends. The book is divided into five parts. The first part introduces the basic principles and related knowledge of the Internet, the fundamental principles of network interconnection, and the basic knowledge of wireless communication networks and technologies. The second part elaborates on the application of data services and IP technology in wireless communication networks such as GSM, IS-136, CDMA IS-95, GPRS, UMTS, cdma2000, and 802.11 wireless local area networks, covering various data services and applications including circuit-switched and packet-switched data services. The third part describes the challenges of using IP in wireless communication networks, the applications that wireless IP networks will provide in the near future, and the evolution of wireless IP networks. The fourth part introduces IP in Bluetooth, Wireless Application Protocol (WAP), and I-Mode. The fifth part covers the standardization organizations in the fields of the Internet and mobile communication networks, as well as their roles. The book is rich in content, easy to understand, well-structured, illustrated with diagrams, and suitable for engineers, application developers, and students in communication engineering and computer science who need to understand IP technology and wireless communication networks. Anyone interested in the convergence trend of wireless communication networks and IP networks is a potential reader of this book.
