In a multidatabase environment with mobile computers involved, the nature of computing is such that the user may not wait for the submitted global transaction to complete before disconnecting from the network. In this paper, a basic architectural framework to support transaction management in multidatabase systems is proposed and discussed. A simple message and queuing facility is suggested which provides a common communication and data exchange protocol to effectively manage global transactions submitted by mobile workstations (MWS). The state of global transactions is modelled through the use of transaction sub-queues. The proposed strategy allows an MWS to submit global transactions and then disconnect itself from the network to perform some other tasks, thereby increasing processing parallelism and independence.<
