Memo, a New Approach to Mobile Data Management

Advances in wireless communication technologies and appearance of powerful portable computers, have led to the emergence of the mobile computing paradigm in which access to information resources is an ever-growing demand. Also, the mobile world has an abundance of options for shrinking databases for use on small devices such as PDAs. Different classes of mobile applications can be distinguished depending on the data management requirements they introduce. The most common applications today are fixed client-fixed host, mobile client-fixed host, and mobile client-mobile host. It could be readily prophesied that mobile host applications will gain popularity with the emergence of ambient intelligence, whatever be the client mobility. In this paper, we introduce movable database servers (mobile servers) along with some related new concepts and components and show how they could be utilized in conjunction with the existing widely accepted model to offer data mobility
