A transaction processing system
Therefore, it has the ability to increase the throughput of mobile transaction processing systems. Our mobile data sharing mechanism provides an adaptable way for increasing data availability, while taking into account all the important characteristics of mobile environments, which are: the mobility of computing hosts, the frequent and unpredictable disconnections of wireless networks, and the resource constraints of mobile computing devices.
Data consistency of the database systems is assured by either serialization of transactions or applying user-defined policies. These shared transactions interact through a mobile sharing workspace, called an export-import repository. The data sharing processes among transactions at different mobile hosts are carried out by shared transactions, called export and import transactions.
The mobile affiliation workgroup model allows mobile hosts to form temporary and dynamic mobile workgroups by taking advantage of wireless communication technologies, i.e., the ability of direct communication among nearby mobile hosts. This is achieved by the concepts of the mobile affiliation workgroup model that focuses on supporting mobile collaborative work in the horizontal dimension. The first contribution is a versatile mobile data sharing mechanism. The results of our research consist of three important contributions: Our solution is to provide the mobile transaction processing system with flexible and adaptable data sharing mechanisms that can cope with the dynamic changes of the surrounding environmental conditions while ensuring data consistency of the database systems. One of the problems is to support the sharing of data among transactions in volatile mobile environments. However, there are still major issues that have not been completely solved. Many research proposals that focus on supporting transaction processing in mobile environments have been developed. On the other hand, these unique characteristics of the mobile environment pose many challenges to mobile transaction processing systems, especially in terms of long delaying periods, data unavailability and data inconsistency. The environment for accessing and processing information is changing rapidly from stationary and location dependent to mobile and location independent. On the one hand, the mobile environment promotes a new working model, i.e., people can carry out their work while being on the move. A mobile environment is different from the traditional distributed environment due to its unique characteristics: the mobility of users or computers, the frequent and unpredictable disconnections of wireless networks, and the resource constraints of mobile computing devices.
