Substantial economies of scale in the production of information goods give reasons for considering the outsourcing of the production. The trade in information goods – resulting from the outsourcing of the production – is a typical transaction which can be analysed using transaction cost theory. Taking into account the particular characteristics of information goods and the process of delivering...

The Common Object Request Broker Architecture standardizes a platformand programming-language-independent distributed object computing environment. It also provides a standard for several distributed services. The Object Transaction Service provides an object-oriented framework for distributed transaction processing, especially for Online Transaction Processing in business applications. The cur...

The characteristics of advanced applications vary a lot and the transaction concept must adapt to fulfil the varying transactional requirements. However, current transaction services do not support the required flexibility in a principled way. We believe that the need for transaction service flexibility can be supported through reflection, where the system is capable of inspecting and changing ...

Open-ended activities are characterized by uncertain duration, unpredictable developments , and interactions with other concurrent activities. Like other database applications, they require consistent concurrent access and fault-tolerance, but their unconventional characteristics are incompatible with the conventional database mechanisms of concurrency and failure atomicity. We present the spli...

Inter-transaction pattern and rule mining has been the subject of active research and has potential application in many areas. All the previous inter-transaction rule mining studies proposed generating a full set of inter-transaction rules (i.e., all frequent and confident rules) from a full set of inter-transaction patterns (i.e., all frequent patterns). However, generating a full set inter-tr...

We propose a unique and hybrid approach containing data mining techniques, artificial intelligence and statistics in a single platform for fraud detection of online financial transaction, which combines evidences from current as well as past behavior. The proposed transaction risk generation model (TRSGM) consists of five major components, namely, DBSCAN algorithm, Linear equation, Rules, Data ...

This chapter outlines and discusses theoretical and methodological foundations for transaction log analysis. We first address the fundamentals of transaction log analysis from a research viewpoint and the concept of transaction logs as a data collection technique from the perspective of behaviorism. From this research foundation, we move to the methodological aspects of transaction log analysis...

We address the problem of maintaining the integrity of large knowledge bases using a compile-time transaction modiication technique. The novelty of the approach lies in the adaptation of ideas from Artiicial Intelligence (AI) planning research. Speciically, starting with the observation that solutions to the frame and ramiication problems can be used during database transaction design time, we ...

This paper presents a framework to process the transactions under the active heterogeneous database systems. In order to perform a correct schedule of transactions with high performance, the framework provides a semantic-based concurrency control on the global level. It relaxes the correct criterion (global serializability) to allow the global sub-transactions on each site to execute in differe...
