A framework for understanding human factors in web-based electronic commerce

The World Wide Web and email are used increasingly for purchasing and selling products. The use of the internet for these functions represents a significant departure from the standard range of information retrieval and communication tasks for which it has most often been used. Electronic commerce should not be assumed to be information retrieval, it is a separate task-domain, and the software systems that support it should be designed from the perspective of its goals and constraints. At present there are many different approaches to the problem of how to support seller and buyer goals using the internet. They range from standard, hierarchically arranged, hyperlink pages to “electronic sales assistants”, and from text-based pages to 3D virtual environments. In this paper, we briefly introduce the electronic commerce task from the perspective of the buyer, and then review and analyse the technologies. A framework is then proposed to describe the design dimensions of electronic commerce. We illustrate how this framework may be used to generate additional, hypothetical technologies that may be worth further exploration.     

Time-bound negotiation framework for electronic commerce agents

For efficient and informative coordination of agents especially in electronic commerce environment, a time-bound agent negotiation framework is proposed utilizing a time-based commitment scheme. By attaching commitment duration to agent messages, the traditional contract net protocol is extended to a time-bound negotiation framework (TBNF). The proposed negotiation framework has a new message type which allows for parties to agree upon the extension of a commitment duration, and a novel commitment concept in the form of negative commitment. The semantics of the messages with the commitment duration are interpreted, and then the three typical negotiation protocols are formally defined and compared — nothing-guaranteed protocol, acceptance-guaranteed protocol, and finite-time guarantee protocol — which can be incorporated into TBNF. The TBNF should provide a background for efficient and effective electronic commerce negotiation while accommodating each agent's adaptive negotiation strategy.     

XPECT: a framework for electronic commerce

Electronic commerce is emerging as one of the most important applications on the Internet, with the potential to revolutionize the whole structure of retail merchandising and shopping. There is already a need for an information technology infrastructure that goes well beyond the simple capabilities offered by the current development environments for Internet applications. For electronic commerce to really take off, however, it will have to give shoppers options not available through traditional commercial channels. This implies the further need for an infrastructure that can support complex and flexible services to manage customer tailored requests in the context of highly dynamic networks and federations of providers. To achieve this level of support will mean using the functionalities now considered to be whole applications as the elementary building blocks of e-commerce applications. Among these functionalities are: transactional payment; workflow; and multiparty agreement. To address these issues, we developed XPect, a generic framework for electronic commerce. The XPect framework supports the integration of multiple component functionalities. It is implemented in the Coordination Language Facility, an object based distributed application development tool. CLF assumes an object model of autonomous agents that can engage in interactions, more sophisticated than those in the traditional object paradigm. In addition, CLF allows for dynamically adding new services and for coordinating the access to multiple services

A reference system for internet based inter-enterprise electronic commerce

As supply chain management and its global outsourcing are widely spread recently, many researches and development focus on integration of inter-enterprise information systems. The most important factors to achieve inter-enterprise integration are standardization and digitalization. The objectives of this work are to develop the reference model for internet based inter-enterprise electronic commerce and to implement a prototype system for its fundamental issues such as business process, information standards, and information system integration. The electronics assembly processes are chosen as the target industry. For the reference architecture of inter-enterprise electronic commerce, we also investigate intra-enterprise business processes and model them with IDEF0. The standard documents and its items are defined from analysis of traditional documents for outsourcing processes and EDI documents. For standard exchange method, web-based XML is adopted, and corresponding DTD and XSL for RFQ and Quotation are developed. In order to prove feasibility and effectiveness of the reference system a prototype system is introduced and implemented.     

Application framework issues when evolving business applications for electronic commerce

When an organization embarks on e-commerce it rarely has a chance to re-engineer its existing business applications. However, if these business applications were built using an application framework, then one might hope to reuse many of the existing legacy applications in the new e-commerce context. How much of the original application can be reused, and how much does the original application framework have to evolve in order to support this reuse? This paper describes our experience with evolving our framework for building engineered-product business applications so that these applications can be delivered over the Internet. We discuss the general issues created by migrating applications to e-commerce, and identify architectural concerns for application frameworks that must support e-commerce.     

Documenting electronic commerce systems and software using the unified modeling language

Electronic commerce (EC) systems are complex systems consisting of cooperating heterogeneous software, hardware and database subsystems that are distributed among processing nodes [1]. They are reactive, real-time and concurrent distributed systems. They are financially critical systems since they perform distributed business functions, the success of which is very critical for the business operation. The use of well-defined specification and documentation techniques is very essential for the effective development and maintenance of these systems. In this paper, we propose the use of the unified modeling language (UML) [2] as a technique for documenting and specifying EC systems at various levels of abstractions and from different views. We believe that the use of UML ensures a better reliability and reusability of these systems.     

An affiliated search system for an electronic commerce and software component architecture

This paper describes an Electronic Commerce Goods Search System (ECGSS) that has functions that increase the precision of search results through training of the search system and uses affiliated business transaction processes. The software component architecture for ECGSS also allows the effective deployment of the system on every local business site, in view of the evolving trend in information technology toward easier configuration and re-usability. A general information gathering system with the infrastructure to accept every Internet communication protocol and access control is described. In this affiliated business transaction model, we classify Internet sites into two groups: a cooperative sites group, and a non-cooperative sites group. While designing the components, we optimized their specifications with respect to the whole architecture analysis, dependencies, and interface types using a component-based software development process. Experiments on the effectiveness of the user training function for the search system and the response time for simple queries for each communication protocol are presented. Comparisons of commercial search solutions and architectural standards of several organizations are also given.     

Empirical taxonomy of services and service products in electronic commerce

In this study, we newly classify services and service products in EC into four categories: Mass Services, Interactive Services, Supporting Services, and Professional Services. Five selected variables reflecting the characteristics of the services, and two factorized dimensions, (1) proportion of on-line services, and (2) need of on-line interaction, are utilized for the classification. In addition, the relationships with customer purchase intentions in EC are investigated as a result of the classification. For this purpose, a customer survey was conducted on respondent groups who frequently purchase goods or services by EC and who also had advanced knowledge of the services and EC. Statistical methods of factor analysis, cluster analysis, and analysis of variance were utilized for analysis of the data.

A flaw in the electronic commerce protocol SET

The Secure Electronic Transaction (SET) protocol has been developed by the major credit card companies in association with some of the top software corporations to secure e-commerce transactions. This paper recalls the basics of the SET protocol and presents a new flaw: a dishonest client may purchase goods from an honest merchant (with the help of another merchant) for which he does not pay. Fortunately, by checking his balance sheet, the merchant may trace with the help of his bank the client and his accomplice. We also propose a modification to fix the flaw.     

A semantic interoperability framework for software as a service systems in cloud computing environments

In cloud computing environments in software as a service (SaaS) level, interoperability refers to the ability of SaaS systems on one cloud provider to communicate with SaaS systems on another cloud provider. One of the most important barriers to the adoption of SaaS systems in cloud computing environments is interoperability. A common tactic for enabling interoperability is the use of an interoperability framework or model. During the past few years, in cloud SaaS level, various interoperability frameworks and models have been developed to provide interoperability between systems. The syntactic interoperability of SaaS systems have already been intensively researched. However, not enough consideration has been given to semantic interoperability issues. Achieving semantic interoperability is a challenge within the world of SaaS in cloud computing environments. Therefore, a semantic interoperability framework for SaaS systems in cloud computing environments is needed. We develop a semantic interoperability framework for cloud SaaS systems. The capabilities and value of service oriented architecture for semantic interoperability within cloud SaaS systems have been studied and demonstrated. This paper is accomplished through a number of steps (research methodology). It begins with a study on related works in the literature. Then, problem statement and research objectives are explained. In the next step, semantic interoperability requirements for SaaS systems in cloud computing environments that are needed to support are analyzed. The details of the proposed semantic interoperability framework for SaaS systems in cloud computing environments are presented. It includes the design of the proposed semantic interoperability framework. Finally, the evaluation methods of the semantic interoperability framework are elaborated. In order to evaluate the effectiveness of the proposed semantic interoperability framework for SaaS systems in cloud computing environments, extensive experimentation and statistical analysis have been performed. The experiments and statistical analysis specify that the proposed semantic interoperability framework for cloud SaaS systems is able to establish semantic interoperability between cloud SaaS systems in a more efficient way. It is concluded that using the proposed framework, there is a significant improvement in the effectiveness of semantic interoperability of SaaS systems in cloud computing environments.     

A novel framework for software defined based secure storage systems

The Software Defined Systems (SDSys) paradigm has been introduced recently as a solution to reduce the overhead in the control and management operations of complex computing systems and to maintain a high level of security and protection. The main concept behind this technology is around isolating the data plane from the control plane. Building a Software Defined System in a real life environment is considered an expensive solution and may have a lot of risks. Thus, there is a need to simulate such systems before the real-life implementation and deployment. In this paper we present a novel experimental framework as a virtualized testbed environment for software defined based secure storage systems. Its also covers some related issues for large scale data storage and sharing such as deduplication. This work builds on the Mininet simulator, where its core components, the host, switch and the controller, are customized to build the proposed experimental simulation framework. The developed emulator, will not only support the development and testing of SD-based secure storage solutions, it will also serve as an experimentation tool for researchers and for benchmarking purposes. The developed simulator/emulator could also be used as an educational tool to train students and novice researchers.
