Information systems are the backbone of many of today's computerized applications. Distributed databases and the infrastructure needed to support them have been well studied. However, this book is the first to address distributed database interoperability by examining the successes and failures, various approaches, infrastructures, and trends of the field. A gap exists in the way that these systems have been investigated by real practitioners. This gap is more pronounced than usual, partly because of the way businesses operate, the systems they have, and the difficulties created by systems' autonomy and heterogeneity. Telecommunications firms, for example, must deal with an increased demand for automation while at the same time continuing to function at their current level. While academics are focusing on investigating differences between distributed databases, federated databases, heterogeneous databases, and, more generally, among loosely connected and tightly coupled systems, those who have to deal with real problems right away know that the only relevant research is the one that will ensure that their system works to produce reasonably correct results. Interconnecting Heterogeneous Information Systems covers the underlying principles and infrastructures needed to realize truly global information systems. The book discusses technologies related to middleware, the Web, workflows, transactions, and data warehousing. It also overviews architectures with a discussion of critical issues. The book gives an overview of systems that can be viewed as learning platforms. While these systems do not translate to successful commercial realities, they push the envelope in terms of research. Successful commercial systems have benefited from the experiments conducted in these prototypes. The book includes two case studies based on the authors' own work. Interconnecting Heterogeneous Information Systems is suitable as a textbook for a graduate-level course on Interconnecting Heterogeneous Information Systems, as well as a secondary text for a graduate-level course on database or information systems, and as a reference for researchers and practitioners in industry.

Product Description: Not many years ago, some researcher created the vision of the 'data utility' as a key enabler towards ubiquitous and pervasive computing. As for the water and power grid, there should be a utility infrastructure, designed for worldwide availability, providing continuous access to persistent information...read more

Incorporates requirements capture and process design. Describes information modelling and management. Discusses design methods and support services for application engineering and management. The technology discussed allows the end-user to bring together purpose-built application components, services delivered by other organisations, off-the-shelf software packages, databases, or databases' legacy software and communications systems. This book is therefore relevant to small companies with network-based information systems and to large organisations seeking to engage in the practice of international electronic commerce. It is also suitable for specialists and postgraduate students working in the fields of software engineering, databases, CSCW, and knowledge-based and distributed systems.

A manual for professional Delphi developers who work with databases and interprogram and network interaction furnishes general information on the architecture of distributed applications, the advantages and disadvantages of various applications, and the processes used to create server and client components using XML, SOAP, WSDL, and UDDI for the Web, ASP.NET, and ADO.NET applications.
