.It concludes that,contrary to common practice in most organizations, one standardized development methodology is not bestsuited for all, or even most, e-business projects.Fifteen variables that are key to identifying the best15 Overviewmethodology for a given e-business project are distilled, and a framework is constructed to aid developmentteams in the process of formulating a customized development methodology to serve as a basis for projectmanagement and control.This framework provides a storehouse of options from which project managers canselect and tailor methodologies to suit their organizational needs including the unique nature of Web-enablede-business.An important key in achieving more effective Web system development within the rapidly changingenvironment will be a design approach that facilitates the creation of architectures that actively encompassboth functional and informational elements, and links it to the business model creating a strong cohesion.Thisrequires an appropriate architectural modeling language and a process for carrying out the architecturaldesign.Chapter 15 by David Lowe and Brian Henderson-Sellers on Characterizing Web Systems: MergingInformation and Functional Architectures, discusses the above aspects, looking at a model of Web systemsthat emphasizes the links between the various architectural elements and process level support for designactivities.In Chapter 16 , Customisation of Internet Multimedia Information Systems Design Through UserModelling, Sherry Y.Chen and Marios C.Angelides attempt to incorporate cognitive and interpersonal stylesinto the design of Internet multimedia information systems.Based on the findings of previous studies, thischapter presents a user model to customize the design of Internet multimedia information systems for differentcognitive and interpersonal styles.This model can help designers to decide which levels of navigation supportand presentational structures work best for different types of users; it can be applied for providingpersonalization for users with different preferences.Also, this chapter discusses the implications for thedesign of Internet multimedia information systems.Chapter 17, A Software Model, Architecture and Environment to Support Web-Based Applications byDavid Kearney and Weiquan Zhao, describes a model, an architecture and an associated Web ApplicationSupport Environment (WASE) that hide the low-level complexity of the existing Web infrastructure and atthe same time empower enterprise Web application programmers in their objective of writing modular andeasily maintainable software applications for electronic commerce.WASE is not a compiler and does notcompletely abstract away the unique features of Web infrastructure.It is being constructed using XMLdocuments in its API to allow the function and configurability of applications to be defined in a Web-likefashion.Chapter 18, XML - Digital Glue for the Modern WorldElectronic Business Standards Fuelling Intra-and Inter-Enterprise Interoperability for Global Collaboration, by Frank Jung, provides informationabout current XML-related standards for the electronic interchange of business documents.It introduces theprinciples of the major standards in this area, such as XML, DTDs, XML Schema, XSL, XSLT, XPath,XPointer, DOM and SAX.Also it explains why XML is not only an ideal data interchange format, but is verylikely to earn its merits as a very effective format for persistently storing XML-based documents required inthe modern e-business world.Finally, the chapter provides a brief introduction to industry initiatives aimed atoptimizing the standardized exchange of business documents, such as BizTalk, and others.Section VII deals with E-Marketing and Virtual Marketplace and consists of four chapters.In Chapter 19, Designing Agent-Based Negotiation For E-Marketing, by V.K.Murthy describes how todesign agent-based negotiation systems in E-marketing.Such a negotiation scheme requires the constructionof a suitable set of rules, called a protocol, among the participating agents.The use of AI planning and thelogic and algebra of specifications to devise multi-agent-based negotiation protocols are explained [ Pobierz całość w formacie PDF ]
