Mobile Databases

·         Recent advances in portable and wireless technology have led to mobile computing, a new dimension in data communication and processing.
·         Portable computing devices coupled with wireless communications allow clients to access data from virtually anywhere and at any time.
·         This feature is especially useful to geographically dispersed organizations.

·         Some of the software problems, which may involve data management, transaction management, and database recovery—have their origins in distributed database systems.


Explanation:

·         It is a distributed architecture where a number of computers, generally referred to as Fixed Hosts (FS) and Base Stations (BS), are interconnected through a high-speed wired network.
·         Fixed hosts are general purpose computers that are not typically equipped to manage mobile units but can be configured to do so.
·         Base stations are Mobile Units' (MU) gateways to the fixed network. They are equipped with wireless interfaces and offer network access services of which mobile units are clients.
