Business integration models in the context of web services.
E-commerce development and applications have
been bringing the Internet to business and marketing
and reforming our current business styles and
processes. The rapid development of the Web, in
particular, the introduction of the semantic web and
web service technologies, enables business
processes, modeling and management to enter an
entirely new stage. Traditional web based business
data and transactions can now be analyzed,
extracted and modeled to discover new business
rules and to form new business strategies, let alone
mining the business data in order to classify
customers or products. In this paper, we investigate
and analyze the business integration models in the
context of web services using a micro-payment
system because a micro-payment system is
considered to be a service intensive activity, where
many payment tasks involve different forms of
services, such as payment method selection for
buyers, security support software, product price
comparison, etc. We will use the micro-payment case
to discuss and illustrate how the web services
approaches support and transform the business
process and integration model.
Issues about the Adoption of Formal Methods for Dependable Composition of Web Services
Web Services provide interoperable mechanisms for describing, locating and
invoking services over the Internet; composition further enables to build
complex services out of simpler ones for complex B2B applications. While
current studies on these topics are mostly focused - from the technical
viewpoint - on standards and protocols, this paper investigates the adoption of
formal methods, especially for composition. We logically classify and analyze
three different (but interconnected) kinds of important issues towards this
goal, namely foundations, verification and extensions. The aim of this work is
to individuate the proper questions on the adoption of formal methods for
dependable composition of Web Services, not necessarily to find the optimal
answers. Nevertheless, we still try to propose some tentative answers based on
our proposal for a composition calculus, which we hope can animate a proper
discussion
Pemanfaatan E-Commerce dengan Metode FAST untuk Strategi Pemasaran pada Zerroart
Implementation of technology in commerce and business is absolutely necessary as a strategy to increase sales and expand marketing through online services in the form of web e-commerce. Zerroart is a distro that tries to take advantage of technology in sales services to compete and increase sales results. Sales conventional during the Covid 19 pandemic are felt to be unable to increase sales results and the number of buyers is limited. This study analyzes the needs of Zerroart in achieving its goals and develops a web-based system using the Framework for the Application of System Thinking (FAST) model. The method used in analyzing uses object-oriented methods with UML modeling. Based on the test results, the e-commerce website can be used easily by users and real-time transactions. The developed web displays features that match the needs of Zerroart where consumers can see all available products, place orders and make payments

Actor perception in business use case modeling
Mainstream literature recognizes the validity and effectiveness of use cases as a technique for gathering and capturing system requirements. Use cases represent the driver of various modern development methods, mainly of object-oriented extraction, such as the Unified Process. Although the adoption of use cases proliferated in the context of software systems development, they are not as extensively employed in business modeling . The concept of business use case is not a novelty, but only recently did it begin to re-circulate in the literature and in case tools.
This paper examines the issues involved in adopting business use cases for capturing the functionality of an organization and proposes guidelines for their identification, packaging, and mapping to system use cases. The proposed guidelines are based on the principle of actor perception described in the paper. The application of this principle is exemplified with a worked example aimed at demonstrating the utility of the proposed guidelines and at clarifying the application of the principle of actor perception. The worked example is based on a series of workshops run at a major UK financial institution
Challenges to describe QoS requirements for web services quality prediction to support web services interoperability in electronic commerce
Quality of service (QoS) is significant and necessary for web service applications quality assurance. Furthermore, web services quality has contributed to the successful implementation of Electronic Commerce (EC) applications. However, QoS is still the big issue for web services research and remains one of the main research questions that need to be explored. We believe that QoS should not only be measured but should also be predicted during the development and implementation stages. However, there are challenges and constraints to determine and choose QoS requirements for high quality web services. Therefore, this paper highlights the challenges for the QoS requirements prediction as they are not easy to identify. Moreover, there are many different perspectives and purposes of web services, and various prediction techniques to describe QoS requirements. Additionally, the paper introduces a metamodel as a concept of what makes a good web service
Value-Oriented Design of Service Coordination Processes: Correctness and Trust
The rapid growth of service coordination languages creates a need for methodological support for coordination design. Coordination design differs from workflow design because a coordination process connects different businesses that can each make design decisions independently from the others, and no business is interested in supporting the business processes of others. In multi-business cooperative design, design decisions are only supported by all businesses if they contribute to the profitability of each participating business. So in order to make coordination design decisions supported by all participating businesses, requirements for a coordination process should be derived from the business model that makes the coordination profitable for each participating business. We claim that this business model is essentially a model of intended value exchanges. We model the intended value exchanges of a business model as e3 -value value models and coordination processes as UML activity diagrams. The contribution of the paper is then to propose and discuss a criterion according to which a service coordination process must be correct with respect to a value exchange model. This correctness is necessary to gain business support for the process. Finally, we discuss methodological consequences of this approach for service coordination process design
Defense against Insider Threat: a Framework for Gathering Goal-based Requirements
Insider threat is becoming comparable to outsider threat in frequency of security events. This is a worrying situation, since insider attacks have a high probability of success because insiders have authorized access and legitimate privileges. Despite their importance, insider threats are still not properly addressed by organizations. We contribute to reverse this situation by introducing a framework composed of a method for identification and assessment of insider threat risks and of two supporting deliverables for awareness of insider threat. The deliverables are: (i) attack strategies structured in four decomposition trees, and (ii) a matrix which correlates defense strategies, attack strategies and control principles. The method output consists of goal-based requirements for the defense against insiders
