Dynamic Inter-Enterprise Workflow Management in a Constraint-Based E-Service Infrastructure

This paper presents an infrastructure and a mechanism for achieving dynamic Inter-enterprise workflow management using e-services provided by collaborative e-business enterprises. E-services are distributed services that can be accessed programmatically on the Internet, using SOAP messages and the HTTP protocol. In this work, we categorize e-services according to their business types and manage them in a UDDI-enabled constraint-based Broker Server. E-service requests are specified in the activities of a process model according to some standardized e-service templates and are bound to the proper service providers at run-time by using a constraint-based, dynamic service binding mechanism. The workflow management system is dynamic in the sense that the actual business organizations, which take part in a business process, are not determined until run-time. We have extended the traditional workflow process modeling by including e-service requests in activity specifications and extended the Web Service Description Language (WSDL) by including constraints in both service specifications and service requests so that the selection of e-service providers can be more accurately performed.

Performance measurement for e-business enterprises

E-business involves a fundamental change in business because it changes business foundations. Thus, companies that are trying to develop e-business capacities need to evaluate whether their current systems for managing enterprises are adequate when new business models appear. This paper considers weaknesses noted by different authors regarding the current performance measurement models and reviews some recent models to discover their suitability in e-business Models. A new system able to facilitate the definition of performance indicators for e-business companies is defined. The Model takes into account high level concepts (customers, strategies, stakeholders, etc) and operational concepts (information, resources, functions and roles) developing an integrated model. The Model is supported by IE-GIP (Enterprise Integration - Business Processes Integrated Management - acronyms in Spanish) methodology and CIMOSA concepts.

E-service em bibliotecas: gera ao de valor para pesquisadores por meio de coopera ao indireta

O conceito de cooperação indireta aplicado a dados de transações de empréstimos do acervo de uma biblioteca pode ser usado para gerar recomendações de itens relevantes para usuários e pesquisadores. O modelo proposto utiliza a Análise de Agrupamentos e a Análise de Cestas e tem aplicabilidade direta em livrarias virtuais, podendo ser adaptado a praticamente qualquer tipo de empreendimento em e-business.

The e-business enterprise and the ‘Web-first’ principle of e-marketing

This paper looks at how an e-business ‘virtual’ enterprise, one primarily reliant on the Internet for all interaction and communication with its audiences, can develop and deploy sophisticated marketing campaigns using the Internet as the principal medium. As such, it outlines the principle of ‘Web-first’ marketing, and draws on practice and experience at Oracle to illustrate the guidelines for ‘Web-first’ engagement and the benefits that such a strategy can deliver. Finally, it looks at the challenges that await e-marketers as the Internet continues to evolve.

E-business architecture design issues

Switching to an enterprise e-business architecture requires hard decisions, but promises many benefits. The paper considers e-business architecture design issues, client server and thin client architectures and the logical services model.
