MANAGEMENT ISSUES AND CHALLENGES IN MOBILE DATABASE SYSTEM

The popularity of the mobile database is increasing day by day as people need information even on the move in the fast changing world. This database technology permits employees using mobile devices to connect to their corporate networks, hoard the needed data, work in the disconnected mode and reconnect to the network to synchronize with the corporate database. With the advent of mobile databases, users can load up their smart phones and Personal Digital Assistant (PDA) with mobile databases to exchange mission-critical data remotely without worrying about time or distance. In this scenario, the data is being moved closer to the applications in order to improve performance and autonomy. This paper focuses on the management issues and challenges faced with mobile database.

The client and server have wireless connections. A cache is maintained to hold frequent data and transactions so that they are not lost due to connection failure. A database is a structured way to organize information. With the advances in mobile technology and portable mobile devices, which include handheld mobile phones, their larger counterpart, personal device assistance and the laptop, are becoming increasingly useful tools for mobile users. Modern technologies have provided portable computers with wire-less interfaces that allow networked communication even while a user is mobile. Wireless networking greatly enhances the utility of a portable computing device. The mobile users can access information independent of their physical location through wireless connections.
