Existence of huge amounts of data on the Web has developed an undeferring need to locate right information at right time, as well as to integrating information effectively to provide a comprehensive source of relevant information. There is a need to develop efficient tools for analyzing and managing Web data, and efficiently managing Web information from the database perspective. The book proposes a data model called WHOM (Warehouse Object Model) to represent HTML and XML documents in the warehouse. It defines a set of web algebraic operators for building new web tables by extracting relevant data from the Web, as well as generating new tables from existing ones. These algebraic operators are used for change detection.

These include recognition accuracy, total cost of ownership, acquisition and processing speed, intrinsic and system security, privacy and legal requirements, and user acceptance.The "Guide to Biometrics:"* Debunks myths and candidly confronts problems associated with biometrics research* Details relevant issues in choosing between biometrics, as well as defining and measuring performance* Defines and explains how to measure the performance of both verification and identification systems* Addresses challenges in managing tradeoffs between security and convenienceSecurity and financial administrators, computer science professionals, and biometric systems developers will all benefit from an enhanced understanding of this important technology.

Based on the needs of the educational community, and the software professional, this book takes a unique approach to teaching software testing. It introduces testing concepts that are managerial, technical, and process oriented, using the Testing Maturity Model (TMM) as a guiding framework. The TMM levels and goals support a structured presentation of fundamental and advanced test-related concepts to the reader. In this context, the interrelationships between theoretical, technical, and managerial concepts become more apparent. In addition, relationships between the testing process, maturity goals, and such key players as managers, testers and client groups are introduced.Topics and features:- Process/engineering-oriented text- Promotes the growth and value of software testing as a profession- Introduces both technical and managerial aspects of testing in a clear and precise style- Uses the TMM framework to introduce testing concepts in a systemmatic, evolutionary way to faciliate understanding- Describes the role of testing tools and measurements, and how to integrate them into the testing process Graduate students and industry professionals will benefit from the book, which is designed for a graduate course in software testing, software quality assurance, or software validation and verificationMoreover, the number of universities with graduate courses that cover this material will grow, given the evoluation in software development as an engineering discipline and the creation of degree programs in software engineering.

The text will provide a comprehensive and pragmatic introduction and advanced reference to the context, definition realization of technical architecture in information and database technology. Covering nearly the full spectrum of architectural concern, we also illustrate and concretize the notion of traceability from business goals, strategy through to technical architecture, providing the reader with a holistic and commanding view. The work has two mutually supportive foci: (a) information technology technical architecture, the in-depth, illustrative and contemporary treatment of which comprises the core and majority of the book; and (b) a strategic and business context, to which a technical architecture tends to enshrine only a partially visible connection. The introduction and description of TOGAF (The Open Group Architectural Framework) as a foundation architecture sets the scene for exploring the notion of the technical reference model, standards information base and the overarching architectural development method.Topics and features: - comprehensive treatment of technical architecture- covers all aspects of the technical architecture development "process"- utilizes a contemporary problems area (E- Business enablement for organizations with an existing IT infrastructure) - provides the motivated reader with practical reference work, written by practicing architects- is an exposition that disseminates precious field heuristics - that is, proven qualitative and quantitative 'rules' that guide information architects in their role

Guide to Successfully Applying the UML offers a tool-independent and process-independent roadmap for successfully applying the Unified Modeling Language (UML). The UML is a modeling language for specifying, visualizing, constructing, and documenting the artifacts of a system-intensive process. It was originally conceived by Rational Software Corporation and three of the most prominent methodologists in the information systems and technology industry: Grady Booch, James Rumbaugh, and Ivar Jacobson. The language has gained significant industry support from various organizations via the UML Partners Consortium and has been submitted to and approved by the Object Management Group as a standard.This book works in concordance with references to offer a suite of practical real-world examples to help novice and expert users of the UML to understand the whole language (holistically and cohesively), including rules of usage and principles of composition, style guidelines, and a roadmap for successfully applying the UML.The examples are presented in a "fairly intuitive/evolutionary" manner that demonstrate the key concepts of the UML and help readers explore the wide range of uses of the UML.

of the Architecture Forum, and to the evolution of TOGAF, to ensure that others make a fair contribution in return. So much for legal necessities. I turn now to the additional information and resources that I hope the reader will ?nd of interest. The Development of TOGAF TOGAF has come a long way since its inception in 1994 at the instigation of The Open Group’s User Council (as it then was)—representatives of the computer user community among The Open Group membership. The original motivations for TOGAF were very much as Tony and Col have expounded so eloquently in the early chapters of this book. The original development of TOGAF was based on the Technical - chitecture Framework for Information Management (TAFIM) developed by the U.S. Department of Defense. The DoD gave The Open Group - plicit permission and encouragement to create TOGAF by building on the TAFIM, which itself represented hundreds of person-years of dev- opment effort and millions of dollars of U.S. government investment. Starting from this sound foundation, the members of The Open Group’s Architecture Forum have developed successive versions of TOGAF over the years and published them on The Open Group’s public Web site. TOGAF-Related Resources The Open Group’s Architecture Forum portal at http://www.opengroup. org/architecture/ provides a ‘‘way in’’ to the information sources - scribed in the remainder of this Foreword. The TOGAF documentation can be viewed freely online at http:// www.opengroup.org/public/arch/.

The emerging Second-Generation Web is based entirely on XML and related technologies. It is intended to result in the creation of the Semantic Web, on which computers will be able to deal with the meaning ("semantics") of Web data and hence to process them in a more effective and autono­ mous way. This new version of the Web introduces a multitude of novel concepts, terms, and acronyms. Purpose, Scope and Methods This dictionary is an effort to specify the terminological basis of emerging XML and Semantic Web technologies. The ultimate goal of this dictionary is even broader than just to define the meaning of newwords - itaims to develop aproper understandingofthese leading-edge technologies. To achieve this, comprehensible definitions of technical terms are supported by numerous diagrams and code snippets, clearly annotated and explained. The main areas covered in this dictionary are: (1) XML syntax and core technologies, such as Namespaces, Infoset and XML Schema; (2) all the major membersofthe XML family oftechnologies, such as XSLT, XPath and XLink; (3) numerous XML-based domain-specific languages, such as NewsML (News Markup Language); (4) the concept and architecture of the Semantic Web; (5) key Semantic Web technologies,such as RDF (Resource Description Framework), RDF Schema and OWL (Web Ontology Language); and (6) Web services, including WSDL (Web Services Description Lan­ guage) and SOAP (Simple Object Access Protocol).

A number of widely used contemporary processors have instruction-set extensions for improved performance in multi-media applications. The aim is to allow operations to proceed on multiple pixels each clock cycle. Such instruction-sets have been incorporated both in specialist DSPchips such as the Texas C62xx (Texas Instruments, 1998) and in general purpose CPU chips like the Intel IA32 (Intel, 2000) or the AMD K6 (Advanced Micro Devices, 1999). These instruction-set extensions are typically based on the Single Instruc­ tion-stream Multiple Data-stream (SIMD) model in which a single instruction causes the same mathematical operation to be carried out on several operands, or pairs of operands, at the same time. The level or parallelism supported ranges from two floating point operations, at a time on the AMD K6 architecture to 16 byte operations at a time on the Intel P4 architecture. Whereas processor architectures are moving towards greater levels of parallelism, the most widely used programming languages such as C, Java and Delphi are structured around a model of computation in which operations takeplace on a single value at a time. This was appropriate when processors worked this way, but has become an impediment to programmers seeking to make use of the performance offered by multi-media instruction -sets. The introduction of SIMD instruction sets (Peleg et al.

The UML, or Unified Modeling Language, is the de facto standard adopted by the Object Management Group (OMG) and by almost all vendors of object modeling tools. The Unified Process is explicitly designed to work with the UML and is a whole design method covering the majority of the life cycle of a software product. John Hunt's book guides you through the use of the UML and the Unified Process and their application to Java systems. Key Topics Focusing explicitly on applying the notation and the method to Java, the book is clearly written to appeal to practitioners. This second edition is considerably revised and extended and includes examples taken from the latest version of Rational Rose and Together. All the UML references are updated to the latest version and the Patterns chapter has been expanded to include J2EE examples. New chapters are included showing how the Unified Process can be used in real world projects and project management, and there is comprehensive coverage of Agile Modeling. - A truly practical introduction to object oriented analysis and design using the Unified Process.
