A transaction model for supporting mobile collaborative works

This paper presents a mobile transaction model for supporting mobile collaborative works. The mobile transaction processing system supports data sharing among mobile hosts via the concept of mobile affiliation workgroups. Data sharing among mobile transactions in a mobile affiliation workgroup is supported by export and import transactions in an export-import repository, which is a mobile sharing workspace. This means that the data sharing process is divided into smaller transaction processes and separated from the main transactions. The mobile transaction system also distinguishes two different mechanisms for supporting data sharing in mobile environments, which are sharing data states and sharing data status.
