For efficiently managing Web Services (WS) transactions which are executed across multiple loosely-coupled autonomous organizations, isolation is commonly relaxed. A Web service operation of a transaction releases locks on its resources once its jobs are completed without waiting for the completions of other operations. However, those early unlocked resources can be seen by other transactions, ...

A Web services operation of a transaction releases locks on its resources once its jobs are completed without waiting for the completions of other operations.

Abstract The aim of this study is to analyse inter-firm corruption and ascertain whether the proximity firms engaged in a significant factor. We draw on transaction cost theory explore two forms corrupt exchange (negotiated vs. productive) role reducing costs. obtained original data from judgements Italian Court Cassation clustered homogeneous proximities. then used separate binomial logistic r...

Multiple systems coupling incurs performance degradation due to inter-system (global) lock conlention and database buffer invalidation. At high transaction rates, the level of inter-syslem interference can have a severe hnpact on performance. In this paper, we propose a scheme for transaction routing lhat reduces inter-system interference while keeping load nearly balanced. The routing decision...

A variety of extensions to the traditional (ACID) transaction model have resulted in a plethora of extended transaction models (ETMs). Many of these ETMs are application-specific, i.e., they are designed to provide correctness guarantees adequate for a particular application, but not others. Similarly, an application-specific ETM may impose restrictions that are unacceptable in one application,...
