Component-based embedded database for mobile embedded systems

摘要

Recent developments in portable devices and growing wireless communication networks have evolved mobile computing during the last few years. Mobile computing enlarges the usability of computers by allowing low powered mobile devices to query the database over the wireless network, but also raises some demanding challenges such as slow expensive connection, frequent line disconnection, limited host bandwidth, location dependent data etc. This database should not only handle transactions with temporal constraints and maintain consistency, but also use small memory footprint. The database should use the resources more efficiently, port on various operating systems, minimize CPU usage, run for long period of time without any user intervention, secure and flexible enough to work with different applications with no or less tailoring. The database should be generic and can be tailored so that the application designer can get fully functional and flexible database for mobile embedded systems. This paper proposes a mobile embedded database, which will resolve some of the important issues caused by the mobile computing environment using a component based approach.
