Enterprise data access from mobile computers: an end-to-end story

Currently, hand-held and palmtop computers are widely used for personal information management. In the near future, they will also be used to access enterprise data. There are however, numerous technical challenges in enabling an end-to-end system that provides enterprise data access from mobile computers. The challenges include heterogeneity, various resource constraints, scalability and security. In this paper, we describe the design and implementation of the Mobile Data Synchronization Service (MDSS), an end-to-end system that provides enterprise data access from mobile computers. Specifically, we address the heterogeneity of devices and data sources, the memory and power constraints of devices, the poor quality of communication and the need for scalability. Our system achieves interoperability and solves the key technical challenges related to enterprise data access from mobile computers.
