Towards a Methodology for the Development of Web-Based Systems: Models, Methods and Activities for Conceptual Design of Large Web-Based Information Systems

Abstract

E-commerce is changing the nature of business. To support ‘buying and selling over digital media’ for private and corporate Web users, companies need not only appropriate transaction systems, but also new information systems. While the systems development challenge for transaction systems is mostly restricted to separating access channel functionality from business transactions processing and developing systems support for new access channels, systems development needs for information systems are much more challenging since different media and different information source systems have to be integrated, novel forms navigation has to be supported and information objects become more complex and more volatile.
