Mobile devices that host embedded database systems are becoming a commonality. Transaction management is needed to provide mobile data availability and transaction processing functionality during disconnection periods. In this paper, we present an adaptation of the transaction correctness criterion GSI to mobile networks that reduces the number of message exchanged per transaction. We discuss t...

Transaction processing systems, whether traditional or Web-based, are prone to error. A “transaction break” occurs when the normal execution process for a transaction has to be suspended because of an unresolved issue. In almost all cases, costly human intervention and negotiation between trading partners is required to solve the problem. There are all sorts of reasons why transaction breaks oc...

The promise of the Internet and e-commerce has led to the increasing use of the web for transaction processing. Many organizations have adopted web-enabled transaction processing for applications such as processing payments online, selling products online, making travel reservations to name a few. In spite of the trend in this direction, transaction processing is not a major application on the ...

Although many extended transaction models have been proposed [Elm93], few practical implementations exist and even fewer can support more than one model. We present the Reflective Transaction Framework, as a practical and modular method to implement extended transaction models. We achieve modularity by applying the Open Implementation approach [Kic92] (also known as meta-object protocol [KdRBSl...

As the e-commerce sites are being more secure and reliable in recent years and the number of transactions is rising rapidly, parallelism can help us to reduce response time and increase throughput for e-commerce transactions. This paper will investigate parallelism in on-line transaction processing. It aims to specify those aspects of e-commerce transactions that would profit from parallel proc...

The evolution of mobile computing device and wireless network has created a new mobile computing environment. Users equipped with portable devices can access, retrieve and process information while in mobility. Mobile devices like laptops; mobile phones become more powerful data processing elements. Traditional transaction model has moved forwarding to mobile transaction. This essay describes t...

The rapid growth of interconnected computer networks has generated a lot of interest in migrating the distributed systems to a wide area network (WAN) environment, such as the Internet. We have developed mechanisms for studying the performance of the distributed transaction processing on the Internet, without actually having to move the database sites to remote Internet hosts. We have conducted...

high availability, database failover, database replication, fault tolerance, transaction processing, three-tier architectures Enterprise applications typically store their state in databases. If a database fails, the application is unavailable while the database recovers. Database recovery is time consuming because it involves replaying the persistent transaction log. To isolate end-users from ...
