Abstract :
The paper describes an approach for enabling remote database access from heterogeneous thin clients. DataX is a proxy based architecture that supports disconnected operation by replicating a subset of the database on the mobile client, using a weak consistency criterion. It adapts data replication to device characteristics, link attributes and user preferences. It employs a per-device renderer to present data in a form layout, making the application logic separate from user interface logic and independent of the device type. It offers small footprint of client-side software, rapid development of end-to-end solutions, and portability across multiple server platforms
