The growth of the Internet and the World Wide Web has already a significant impact on business, industry, education, entertainment sectors, and our personal and working life. At present electronic commerce (e-commerce) is one of the fastest growing technologies that have evolved in a remarkably short time. A wide range of new, complex distributed applications is emerging in the e-commerce environment, most notably, eshops, e-auctions, e-catalogs, supply chain management systems, agent systems. This has led to the development of new e-commerce architectures and infrastructures, Web data models, cooperation and negotiation models, and security mechanisms. It is almost impossible to keep track of all new architectures, technologies, and approaches launched during the last few months. According to our knowledge, there is no foundation of research or experience here in Indonesia to underpin these e-commerce based business models and architectures, and most companies are forced to select e-commerce architectures on an ad hoc basis. While e-commerce is growing rapidly, there are several open issues that must be resolved if its full potential is to be implemented. These issues are the implications of the open nature of the Internet on business-to-business and business-to-consumer relationships, security of enterprise data and systems, and ensuring connectivity across enterprises. All of these aspects need to be investigated in order to build reliable e-commerce architectures. We argue that neither the problem, nor principles, methods, and techniques for the systematic engineering of e-commerce architectures are fully understood. To achieve a better understanding of the problems, available e-commerce architectures have to be investigated. The main goal of our talk is to define principles, methods, and techniques to assist in the systematic engineering of e-commerce architectures to facilitate the development of e-commerce and Web-based information systems. Security is a critical component of any e-commerce application and must be addressed in designing any e-commerce architecture. Thus, the challenge here is to investigate the integration of information and communication security mechanisms in close cooperation with the enterprise security research area.F.
