The Internet and the proliferation of inexpensive computing power in the form of clusters of workstations or PCs provide the basic hardware infrastructure for business to business electronic commerce in small and medium enterprises. Unfortunately, the corresponding software infrastructure is still missing. In this paper we show a way to develop appropriate tools for electronic commerce by descr...

Efforts to improve enterprise performance depend to a large extent on models of enterprise processes created for analysis and design. This paper describes a modeling scheme which supports the development of a multi-view model of an enterprise and its processes. The paper first presents an overview of the efforts such as business process reengineering, enterprise integration, and enterprise engi...

In this paper, we examine two modern enterprise Flash-based solid state devices and how varying usage patterns influence the performance one observes from the device. We observe that in order to achieve peak sequential and random performance of an SSD, a workload needs to meet certain criteria such as high degree of concurrency. We measure the performance effects of intermediate operating syste...

Use of mobile computing devices such as laptops, PDAs, and Wi-Fi enabled phones is increasing in the workplace. As the usage of corporate 802.11 wireless networks (WLANs) grows, network performance is becoming a significant concern. We have built DenseAP, a novel system for improving the performance of enterprise WLANs using a dense deployment of access points (APs). In sharp contrast with wire...

Social networking websites are currently used by many people, especially young ones who are in the age group of 17–25. Since these age groups are mostly students and are either college going or in the process of making a career, it is difficult for the parents to keep a close watch over their activities. Even the academic coordinators and advisors have not developed a pattern through which thes...

In this paper a methodology to develop simulation models is presented. The methodology is based on a multi-level simulation model which allows flexibility and process analysis. The present work starts from applied researches in different SME enterprises. Enterprise management often needs easy and fast developed tools to increase production capacity and flexibility. In many cases performances in...

A performance measurement system (PMS) is a decision support system that through a set of indicators allows an analysis the current state of an enterprise and to compare it with the strategic objectives. It is therefore a fundamental tool for management control in business.

Understanding the performance characteristics of enterprise applications, such as response time, throughput, and resource utilization, is crucial for satisfying customer expectations and minimizing costs of application hosting. Enterprise applications are usually based on a large set of existing software (e.g. middleware, legacy applications, and third party services). Furthermore, they continu...

The flexibility offered by an Enterprise Service Bus (ESB) in enabling various applications to exchange data makes it a very important middleware layer that is responsible for transporting data in a Service-Oriented Architecture (SOA). The popularity of the ESB has given rise to a number of commercial off the shelf (COTS) products as well as open source ESBs. In this study, we evaluated three o...

Business performance is affected by the quality management practices of the organization. Holistic programs, including the national quality award programs, six-sigma initiatives, and enterprise resource planning (ERP) applications may characterize the highest level of quality initiatives. Arguably, the most popular quality initiative is the ISO 9000 program. The effect of different levels of qu...
