Introduces the mobile databases (their architecture and features) and how they operate and handle the essential task of synchronization. Explains how the enterprise work force can move to a handheld device and still have easy access to corporate databases. Web site contains all source code for working examples of applications showing mobile databases in use. Foreword and endorsement by Bill Inmon, the "Father of Data Warehousing."

This book constitutes the thoroughly refereed postproceedings of the 3rd and 4th International Workshop on Databases, Information Systems and Peer-to-Peer Computing, DBISP2P 2005 and DBISP2P 2006, held in Trondheim, Norway, in August 2005 and in Seoul, Korea, in September 2006, as satellite events of VLDB, the International Conference on Very Large Data Bases.

A major theme of this book is the use of computers for supporting collaborative learning. This is not surprising since computer-supported collaborative learning has become both a widespread educational practice and a main domain of research. Moreover, collaborative learning has deep roots in Asian educational traditions. Given the large number of researchers within this field, its scope has become very broad. Under this umbrella, one finds a variety of more specific topics such as: interaction analysis, collaboration scripts (e.g. the Jigsaw script), communities of practice, sociocognitive conflict resolution, cognitive apprenticeship, various tools for argumentation, online discussion or collaborative drawing tools (whiteboards), collaborative writing and the role of facilitators. Most research work on collaborative learning focuses on interactions rather than on the contents of environments, which had been the focus in the previous decades of learning technology research. However, there is no reason to focus on one aspect to the detriment of the other. The editors are pleased that the selected papers also cover multiple issues related to the storage, representation and retrieval of knowledge: ontologies for learning environments and the semantic web, knowledge bases and data mining, meta-data and content management systems, and so forth. This publication also reveals a growing interest for non-verbal educational material, namely pictures and video materials, which are already central to new popular web-based applications. This book includes contributions that bridge both research tracks, the one focusing on interactions and the other on contents: the pedagogical use of digital portfolios, both for promoting individual reflections and for scaffolding group interactions.

This is the second of a two-volume set that constitutes the refereed proceedings of the Symposium on Human Interface 2007, held in Beijing, China in July 2007. It covers communication and collaboration, knowledge, learning and education, mobile interaction, interacting with the world wide web and electronic services, business management and industrial applications, as well as environment, transportation and safety.

Mobile Computing is designed to serve as a textbook for students in the disciplines of computer science and engineering, electronics and communication engineering, and information technology. It describes the basic concepts of mobile computing and provides technical information about the various aspects of the subject as also the latest technologies that are currently in use. The first few chapters present a balanced view of mobile computing as well as mobile communication, including the 2G and 3G communication systems, mobile IP, and mobile TCP. The subsequent chapters provide a systematic explanation of mobile computing as a discipline in itself. The book provides an in-depth coverage of databases in mobile systems, methods of data caching, dissemination and synchronization, Bluetooth, IrDA and ZigBee protocols, data security, mobile ad hoc and wireless sensor networks, and programming languages and operating systems for mobile computing devices. Written in an easy-to-understand and student-friendly manner, the book includes several illustrative examples and sample codes. A comprehensive set of exercises is included at the end of each chapter
