In this era of pervasive computing, computation platforms have extended to small intelligent devices like cell phones, sensors, smartcards, PDA's (personal digital assistants) etc. Miniature or small size computing machines have become unavoidable and are being equipped with an increasing amount of storing and computing resources. As better, efficient and advanced functionalities and features are being added to these devices, an increasing number of applications are being added and for this we need a paradigm shift to the newer aspect of databases.
