Increase in handy and small electronic devices in computing fields; it makes the computing more popular and useful in business. Tremendous advances in wireless networks and portable computing devices have led to development of mobile computing. Support of real time database system depending upon the timing constraints, due to availability of data distributed database, and ubiquitous computing pull the mobile database concept, which emerges them in a new form of technology as mobile distributed real-time database systems. Processing of transaction with mobility as well as time constraints has opened up a new area of research with a number of design issues such as network connectivity, storage capacity, scheduling, data consistency, data replication & distribution, concurrency control & commit processing, reliability, security, economical aspect, etc.
