The Electronic Communications and Transactions Act of 2002 contain comprehensive on-line consumer protection provisions. In addition, the ECT Act offers safeguards and remedies for natural persons transacting with electronic agents. Yet, the dividing line between consumer transactions and automated transactions is spurious. More often than not, a transaction will fall within both the ambit of a...

This paper investigates preferences and choices in automated transaction dialogues. A transaction dialogue involves obligations of both parties: the system or supplier should present all relevant information; the user or customer is bound by a transaction, once it is con-rmed. However, the transaction is conditional on the preferences and choices that were expressed in the dialogue. Connrmation...

Transaction processing is of growing importance for mobile computing. Booking tickets, flight reservation, banking, ePayment, and booking holiday arrangements are just a few examples for mobile transactions. Due to temporarily disconnected situations the synchronisation and consistent transaction processing are key issues. Serializability is a too strong criteria for correctness when the semant...

Workflow management applications require advanced transaction management that is not offered by traditional database systems. For this reason, a number of extended transaction models has been proposed in thepast. None of these models seems completely adequate, though, because workflow management requires different transactional semantics on different process levels. In the WIDE ESPRIT project, ...

Agrifood supply networks are dynamic structures where firms regularly face the need to search for new market partners. A decision for a transaction with a new partner requires appropriate control and safeguard mechanisms as well as trust to overcome perceived risk and uncertainties. Electronic transaction environments offer new potentials for the identification of new transaction partners. Howe...

In Grid environment, transaction must have the abilities to coordinate both short-lived operations and long-lived business activities, which can not directly be supported by traditional distributed transaction mechanisms. This paper introduces a transaction model based on agent technologies to satisfy these requirements. The model can coordinate both Atomic transaction and Compensation transact...

In this paper the ways of various types of transaction support in the buffer system of the storage system are considered. Support of active transaction tree as the mechanism for nested transaction execution is described. It is shown that inclusion of some additional information into ATT nodes makes possible to support the wide range of flexible transaction concepts. The implementing of ARIES me...

Issues of multidatabase transaction management within the Web are addressed. After examining the nature of the problem and reviewing current solutions, we argue that the classic ACID test of transaction correctness is not appropriate for Web transactions and propose new criteria based on SACReD properties. A new Web Transaction Model (WebTraM), based upon open and closed nested transaction mode...

Atomic transactions are needed to preserve the consistency in the presence of failures and/or concurrency in distributed systems. In this paper we describe an atomic transaction framework which includes class hierarchies for several transaction semantics. The transaction framework has been carefully designed to include the common patterns of transactions. The framework addresses dynamic configu...

This brief announcement focuses on interoperability of software transactions with ad hoc nonblocking algorithms. Specifically, we modify arbitrary nonblocking operations so that (1) they can be used both inside and outside transactions, (2) external uses serialize with transactions, and (3) internal uses succeed if and only if the surrounding transaction commits. Interoperability enables seemle...
