Users can access internet resources using handheld device to connect to internet through wireless network. But there is still some causes in handheld device and wireless network such as environment effect, performance, reliability, costs of connection, and finite energy resource.
To improve the wireless network in handheld device more efficient, distributed file system technologies and web information present technologies are studied. In mobile information access, the detail of contents to be displayed is considered to improve.
In this thesis, a coordinate mechanism with a handheld device and remote server is proposed. The partial database concept is also proposed. In the system, handheld device use agents to manage local database and connect to remote agent. Remote agent receives data and query remote database. The local database is designed using partial detailed concept. Handhels device can store different details of content for query to avoid unnecessary connection to reduce resource wasting. By an dictionary application implementation to verity the efficiency and the mechanism is practicable.
