Abstract or Description

Transaction processing systems lie at the core of modern e-commerce applications such as on-line retail stores, banks and airline reservation systems. The economic success of these applications depends on the ability to achieve high user satisfaction, since a single mouse-click is all that it takes a frustrated user to switch to a competitor. Given that system resources are limited and demands are varying, it is difficult to provide optimal performance to all users at all times. However, often transactions can be divided into different classes based on how important they are to the online retailer. For example, transactions initiated by a "big spending" client are more important than transactions from a client that only browses the site. A natural goal then is to ensure short delays for the class of important transactions, while for the less important transactions longer delays are acceptable.
