Database is the well-organized collection of data in a meaningful way that user can perform the transaction. Transaction is a sequence of many actions considered to be atomic. In the coming months or years you will probably be implementing applications for multiple users to use across a network. Client/server environments are designed specifically for this purpose. Traditionally, a server (in t...

The problem of mining sequential patterns was recently introduced in [3]. We are given a database of sequences, where each sequence is a list of transactions ordered by transaction-time, and each transaction is a set of items. The problem is to discover all sequential patterns with a user-speci ed minimum support, where the support of a pattern is the number of data-sequences that contain the p...

The problem of mining sequential patterns was recently introduced in [AS95]. We are given a database of sequences, where each sequence is a list of transactions ordered by transaction-time, and each transaction is a set of items. The problem is to discover all sequential patterns with a user-speci ed minimum support, where the support of a pattern is the number of data-sequences that contain th...

nowadays, the most controversial issue is transaction in database systems or web services. Specifically, in the area of service-oriented computing, where business transactions always need long periods of time to finish. In the case of a failure rollback, which is the traditional method, it will not be enough and not suitable for handling errors during long running transactions. As a substitute,...

‘Computer-Supported Cooperative Work’ (CSCW) is a young, interdisciplinary research area considering applications with strong demands on multiple fields of computer technology, e.g., distributed systems and networks or multi-media systems. In this paper, we will be focusing on the information-sharing and the corresponding activity-control aspect. Here, the conventional transaction concept of da...

A business process based view of inter-firm relationship is proposed and discussed in this paper. The authors define inter-firm relationships as a broad range of relationships including strategic alliances, joint ventures, and mergers and acquisitions (M&A) or other equity-based relationships in this paper. Inter-firm relationships are some of the most important strategic activities in the pres...

In this paper a modelling methodology for business systems simulation is introduced. The methodology is based on the business transaction concept in conjunction with Petri nets notations. Next to these two components, the Arena simulation package is discussed to build an animated simulation model. Since the simulation model will be demonstrated using the software, it is not included into this p...

A portfolio optimization problem consists of maximizing an expected utility function of n assets. At the end of a typical time period, the portfolio will be modified by buying and selling assets in response to changing conditions. Associated with this buying and selling are variable transaction costs that depend on the size of the transaction. A straightforward way of incorporating these costs ...

This paper focuses on ex post governance of inter-firm transactions. We develop and test hypotheses on the occurrence of ex post problems like delivery delays, inferior quality, and insufficient service in buyer–supplier transactions. Our hypotheses address effects of transaction characteristics, of social embeddedness, and of contractual governance on the occurrence of problems. Other than ear...
