ADVANCES IN DATABASE SYSTEMS

Opis produktu

Information systems are the backbone of many of todays 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. br/ 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 emreal/em problems right away know that the only relevant research is the one that will ensure that their system works to produce reasonably correct results. br/ emInterconnecting Heterogeneous Information Systems/em 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. br/ emInterconnecting Heterogeneous Information Systems/em is suitable as a textbook for a graduatelevel course on Interconnecting Heterogeneous Information Systems as well as a secondary text for a graduatelevel course on database or information systems and as a reference for researchers and practitionerInformation systems are the backbone of many of todays computerized applications.
