Companies and other organizations depend more than ever on the availability of their Information Technology, and most mission critical business processes are IT-based processes. Business continuity is the ability to do business under any circumstances and is an essential requirement modern companies are facing. High availability and disaster recovery are contributions of the IT to fulfill this requirement. And companies will be confronted with such demands to an even greater extent in the future, since their credit ratings will be lower without such precautions.

Both, high availability and disaster recovery, are realized by redundant systems. Redundancy can and should be implemented on different abstraction levels: from the hardware, the operating system and middleware components up to the backup computing center in case of a disaster. This book presents requirements, concepts, and realizations of redundant systems on all abstraction levels, and all given examples refer to UNIX and Linux systems.

Poor data quality can seriously hinder or damage the efficiency and effectiveness of organizations and businesses. The growing awareness of such repercussions has led to major public initiatives like the "Data Quality Act" in the USA and the "European 2003/98" directive of the European Parliament.

Batini and Scannapieco present a comprehensive and systematic introduction to the wide set of issues related to data quality. They start with a detailed description of different data quality dimensions, like accuracy, completeness, and consistency, and their importance in different types of data, like federated data, web data, or time-dependent data, and in different data categories classified according to frequency of change, like stable, long-term, and frequently changing data. The book's extensive description of techniques and methodologies from core data quality research as well as from related fields like data mining, probability theory, statistical data analysis, and machine learning gives an excellent overview of the current state of the art. The presentation is completed by a short description and critical comparison of tools and practical methodologies, which will help readers to resolve their own quality problems.

This book is an ideal combination of the soundness of theoretical foundations and the applicability of practical approaches. It is ideally suited for everyone – researchers, students, or professionals – interested in a comprehensive overview of data quality issues. In addition, it will serve as the basis for an introductory course or for self-study on this topic.

Designing and Building Enterprise DMZs covers a sorely needed area in critical business infrastructure: the Demilitarized Zone. DMZs play a crucial role in any network consisting of a Hosted Internet Web Server, internal servers which need to be segregated, External to Internal DNS Server, and an E-mail SMTP Relay Agent. This book covers what an administrator needs to plan out and integrate a DMZ into a network for small, medium, and Enterprise networks. The primary role of a DMZ is to mitigate risks associated with offering services to untrusted clients. A DMZ accomplishes this by providing network-level protection for a hosting environment, as well as segregating public hosting facilities from the private network infrastructure. This small but very important segment of the network is the section exposed to the public Internet and is the most difficult area on the network to create, and maintain both from an Engineering standpoint and a security standpoint. In this book (the only one of its kind) readers will learn how to make DMZs utilizing the IT world's best of breed software and hardware products from Microsoft, Sun, Cisco, Nokia, and Check Point..
