ABSTRACT
The entire mobile database system processing paradigms is relatively new born out of the needs of highly mobile workers. In the beginning the workforce satisfied their data processing needs by filling their laptops with relevant parts of the database before they set on trip. At the end or sometime in the middle of the trip also then refreshed the main database with up to date data values. In addition, the persistent background nagging of cell phone users for ubiquities access to desired data added additional urgency for the development of a system which came to be known as Mobile Database System (MDS). Members of these communities-from academic as well as from industries-accepted the challenge and created a new research direction with several names such as pervasive computing, ubiquitous computing, nomad computing, anywhere anytime computing. The excitement to write this book morphed into a lot of difficulties. A central problem is the immaturity of research findings. Most of these, such as mobile database transaction models, concurrency control mechanism, recovery protocol, location dependent data, etc. have not been fully deployed and validated in real world. As mobile database technology is deployed, a plethora of useful application will be developed and deployed making MDS an essential gadget for most of us. All other topics such as concurrency control, database recovery, data broadcast, broadcast disks, etc., have been discussed in a similar style.
