Current electronic commerce recommendation system is designed for single electronic commerce website and current recommendation technologies have obvious deficiencies Centralized recommendation systems can not resolve the contradiction between high recommendation quality and timely response, as well as that between limited recommendation range and ever rich information on the web. Distributed recommendation systems are expected to improve the recommendation quality while maintaining high performance. This paper analyses the problems of traditional electronic commerce recommendation system and clarifies the advantage of applying grid technology into electronic commerce recommendation system. It discusses the prototype of an intelligent recommendation system, namely grid based electronic commerce recommendation system (GBECRS). The paper analyses rationale and mechanism of GBECRS and designs its logical structure. It focuses on the design of grid services which are needed to be deployed into electronic commerce recommendation grid. Finally it does deep analysis of key technologies that are applied in the system. Full article

eHealth processes are data-focused, event-driven, and dynamic. They are systematically monitored for compliance with legislation, organizational guidelines and quality of care protocols. Community care, especially at home care, frequently requires the cooperation and integration of care processes across several providers and organizations. Service Oriented Architecture (SOA) through Web services and business process automation through Business Process Execution Language (BPEL) is emerging as a framework for business process integration over the Internet, but does not address all information management requirements of eHealth monitoring processes particularly with respect to policy compliance and event-based data integration. In this paper, we extend the traditional SOA framework to define a flexible policy-based approach for defining and monitoring streaming event data based on a general publish/subscribe model in a business-to-business (B2B) healthcare network. The work described here is design-oriented research where the purpose is to show the utility of the proposed framework. The approach is evaluated based on information management requirements drawn from a case study of palliative care and a prototype implementation. Full article

An Input validation can be a critical issue. Typically, a little attention is paid to it in a web development project, because overenthusiastic validation can tend to cause failures in the software, and can also break the security upon web applications such as an unauthorized access to data. Now, it is estimated the web application vulnerabilities (such as XSS or SQL injection) for more than two thirds of the reported web security vulnerabilities. In this paper, we start with a case study of the bypassing data validation and security vulnerabilities such as SQL injection and then go on to discuss the merits of a number of common data validation techniques. We also review the different solutions to date to provide data validation techniques in ecommerce applications. From this analysis, a new data validation service which is based upon semantic web Technologies, has been designed and implemented to prevent the web security vulnerabilities at the application level and to secure the web system even if the input validation modules are bypassed. Our semantic architecture consists of the following components: RDFa annotation for elements of web pages, interceptor, RDF extractor, RDF parser, and data validator. The experimental results of the pilot study indicate that the proposed data validation service might provide a detection, and prevention of some web application attacks. Full article

Design patterns, acting as recurring solutions to common problems, offer significant benefits such as avoiding unnecessary complexity, and promoting code reuse, maintainability and extensibility. This paper describes how four not technology-specific or language-specific design patterns (Front Controller, Model View Controller, Transfer Object and Service to Worker) can be applied to one typical e-commerce application developed using Java EE platform. The first goal is to evaluate the improvement of design properties after the implementation of each design pattern using software metrics. Another goal is to assess the influence of design patterns on the maintainability of the e-commerce application under study by examining the evolution of software metrics when performing certain extensions. The results indicate that the application of patterns positively influences design properties such as coupling, complexity and messaging implying a possible improvement in high-level quality attributes such as flexibility, extensibility and reusability.

Increased attention to the economic impact of information and communication technologies (ICT) underscores the impact of ICT on the social side of the “digital divide.” ICT and individual and organizational changes are often closely related. This paper examines the main characteristics of the relationship between ICT and human resources in Spanish firms, in the context of a developed country with an incidence-rate of ICT slightly below the average of its area. The data on 1,269 Spanish manufacturing firms has been taken from the Survey of Business Strategies (SBS) of the Fundación Empresa Pública (Spanish Foundation) of Spain. Our results suggest that ICT are related to higher levels of qualification, higher levels of R&D workers, and higher levels of training per worker. Moreover, firms that invest in ICT offer higher levels of average wages. These results confirm the relationship between technological innovation, and organizational and human changes. Managers and public administrators should take into account such mutual interrelations in order to optimize their decisions concerning investment in human and technological resources. Full article

This paper explores the application of Activity-Based Costing and Activity-Based Management in ecommerce. The proposed application may lead to better firm performance of many companies in offering their products and services over the Internet. A case study of a fictitious Business-to-Customer (B2C) company is used to illustrate the proposed structured implementation procedure and effects of an Activity-Based Costing analysis. The analysis is performed by using matrixes in order to trace overhead. The Activity-Based Costing analysis is then used to demonstrate operational and strategic Activity-Based Management in e-commerce. Full article
