Database Systems and Query Processing in Mobile Environment: A Survey

The mobile devices became effective seeds of information, which are thrown to world through various platforms like social networking, cloud computing, peer-to-peer communications and so on. Such information has been transformed in form of databases and further utilised to nurture the queries from other users. Databases are generally kept on the powerful and reliable workstations, so called servers and hence client-server architecture became very well-known in database field. In recent era, mobile devices are transformed in more powerful computing devices on which the various small-sized databases are stored e. g. , phone-book, address-book, system settings etc. This motivates us to explore the mobile database systems and how the effective query processing is to be implemented on those systems. The main contributions of this survey include (a) the exploration of mobile applications, (b) the applicability of mobile databases and (c) the effective query processing approaches in mobile databases.
