Interoperability of Information Systems and Heterogenous Databases Using XML
Interoperabilily of information systerrrs is the most critical issue facing businesse!
that need to access information from multiple idormution systems on
tlifferent environments ancl diverse platforms. Interoperability has been a basic
requirement for the modern information systems in a competitive and volatile
business environment, particularly with the advent of distributed network system
and the growing relevance of inter-network communications. Our objective
in tltis paper is to develop a comprehensiveframework tofacilitate interoperability
smong distributed and heterogeneous information systems and to develop prototype
software to validate tlte application of XML in interoperability of infurmation
systems and databases
An Architecture for Information Commerce Systems
The increasing use of the Internet in business and commerce has created a number of new business opportunities and the need for supporting models and platforms. One of these opportunities is information commerce (i-commerce), a special case of ecommerce focused on the purchase and sale of information as a commodity. In this paper we present an architecture for i-commerce systems using OPELIX (Open Personalized Electronic Information Commerce System) [11] as an example. OPELIX provides an open information commerce platform that enables enterprises to produce, sell, deliver, and manage information products and related services over the Internet. We focus on the notion of information marketplace, a virtual location that enables i-commerce, describe the business and domain model for an information marketplace, and discuss the role of intermediaries in this environment. The domain model is used as the basis for the software architecture of the OPELIX system. We discuss the characteristics of the OPELIX architecture and compare our approach to related work in the field
Mapping service components to EJB business objects
The emerging trends for e-business engineering revolve around specialisation and cooperation. Successful companies focus on their core competencies and rely on a network of business partners for the support services required to compose a comprehensive offer for their customers. Modularity is crucial for a flexible e-business infrastructure, but related requirements seldom reflect on the design and operational models of business information systems. Software components are widely used for the implementation of e-business applications, with proven benefits in terms of system development and maintenance. We propose a service-oriented componentisation of e-business systems as a way to close the gap with the business models they support. Blurring the distinction between external services and internal capabilities, we propose a homogeneous model for the definition of e-business applications components and present a process-based technique for component modelling. We finally present an Enterprise Java Beans extension that implements the model
A language for information commerce processes
Automatizing information commerce requires languages to represent the typical information commerce processes. Existing languages and standards cover either only very specific types of business models or are too general to capture in a concise way the specific properties of information commerce processes. We introduce a language that is specifically designed for information commerce. It can be directly used for the implementation of the processes and communication required in information commerce. It allows to cover existing business models that are known either from standard proposals or existing information commerce applications on the Internet. The language has a concise logical semantics. In this paper we present the language concepts and an implementation architecture
Interoperable Systems: an introduction
This short chapter introduces interoperable systems and attempts to distinguish the principal
research strands in this area. It is not intended as a review. Significant review material is
integrated with each of the succeeding chapters. It is rather intended to whet the appetite for
what follows and to provide some initial conceptual orientation.
This book concerns the architecture, modelling and management of interoperable computing
systems. Our collective research agenda addresses all aspects of interoperable systems
development, including the business and industry requirements and environments for
distributed information services
Object-Oriented Business Solutions
This report summarises the presentations, discussions, and main results of the ECOOP’01 Workshop on Object-Oriented Business Solutions (WOOBS).
It was not a pure scientific meeting, but a mixed gathering where people from the industry and the academia met to exchange ideas, experiences and build a network of relationships with others committed to the emergence of object-oriented business solutions. WOOBS had an invited talk on quality of service, twelve presentations and lively discussions during and after them. The main conclusions were on the importance of Multi-Organisational Web-Based Systems in today’s e-commerce world, which justifies the study of a new multidisciplinary paradigm called Web-Oriented Programming
