XML has become the lingua franca for representing business data, for exchanging information between business partners and applications, and for adding structure
and sometimes meaning to text-based documents. XML offers some special challenges and opportunities in the area of search: querying XML can produce very precise, fine-grained results, if you know how to express and execute those queries.
For software developers and systems architects: this book teaches the most useful approaches to querying XML documents and repositories. This book will also help managers and project leaders grasp how querying XML fits into the larger context of querying and XML. Querying XML provides a comprehensive background from fundamental concepts (What is XML?) to data models (the Infoset, PSVI, XQuery Data Model), to APIs (querying XML from SQL or Java) and more.
* Presents the concepts clearly, and demonstrates them with illustrations and examples; offers a thorough mastery of the subject area in a single book.
* Provides comprehensive coverage of XML query languages, and the concepts needed to understand them completely (such as the XQuery Data Model).
* Shows how to query XML documents and data using: XPath (the XML Path Language); XQuery, soon to be the new W3C Recommendation for querying XML; XQuery's companion XQueryX; and SQL, featuring the SQL/XML
* Includes an extensive set of XQuery, XPath, SQL, Java, and other examples, with links to downloadable code and data samples."

Nancy A. Lynch
R2,966 R2,452 Discovery Miles 24 520 Save R514 (17%) Shipped within 7 - 12 working days

In "Distributed Algorithms," Nancy Lynch provides a blueprint for designing, implementing, and analyzing distributed algorithms. She directs her book at a wide audience, including students, programmers, system designers, and researchers.

"Distributed Algorithms" contains the most significant algorithms and impossibility results in the area, all in a simple automata-theoretic setting. The algorithms are proved correct, and their complexity is analyzed according to precisely defined complexity measures. The problems covered include resource allocation, communication, consensus among distributed processes, data consistency, deadlock detection, leader election, global snapshots, and many others.

The material is organized according to the system model first by the timing model and then by the interprocess communication mechanism. The material on system models is isolated in separate chapters for easy reference.

The presentation is completely rigorous, yet is intuitive enough for immediate comprehension. This book familiarizes readers with important problems, algorithms, and impossibility results in the area: readers can then recognize the problems when they arise in practice, apply the algorithms to solve them, and use the impossibility results to determine whether problems are unsolvable. The book also provides readers with the basic mathematical tools for designing new algorithms and proving new impossibility results. In addition, it teaches readers how to reason carefully about distributed algorithms to model them formally, devise precise specifications for their required behavior, prove their correctness, and evaluate their performance with realistic measures."

Joe Celko
R811 Discovery Miles 8 110 Shipped within 7 - 11 working days

Perfectly intelligent programmers often struggle when forced to work with SQL. Why? Joe Celko believes the problem lies with their procedural programming mindset, which keeps them from taking full advantage of the power of declarative languages. The result is overly complex and inefficient code, not to mention lost productivity.
This book will change the way you think about the problems you solve with SQL programs.. Focusing on three key table-based techniques, Celko reveals their power through detailed examples and clear explanations. As you master these techniques, you ll find you are able to conceptualize problems as rooted in sets and solvable through declarative programming. Before long, you ll be coding more quickly, writing more efficient code, and applying the full power of SQL
Filled with the insights of one of the world s leading SQL authorities - noted for his knowledge and his ability to teach what he knows.
Focuses on auxiliary tables (for computing functions and other values by joins), temporal tables (for temporal queries, historical data, and audit information), and virtual tables (for improved performance).
Presents clear guidance for selecting and correctly applying the right table technique."

They describe practical methods of using SQL to solve problems, advanced SQL query expressions, dynamic SQL, transaction models, and database design. Beginning with a tutorial on basic relational database concepts, subsequent chapters develop SQL and clarify the differences between SQL-89 and SQL-92. Throughout, a retail video and music store is used as an example that develops with the SQL presentation. The book is enhanced by a complete dynamic SQL example, coverage of international character sets, and a look at future generations of SQL. Whether you're a newcomer to SQL or an experienced programmer using PCs, workstations, mini- or mainframes, Understanding the New SQL is an essential resource for current and future implementation of SQL.

Information science is the study of information phenomena, including the acquisition, storage, and manipulation of data, information, and knowledge. It is by nature an interdisciplinary field. Researchers, managers, system users, and students need access to tools, terms, and techniques that are spread out over a large literature in a number of different disciplines: information retrieval, database management, office information systems, information technology, communication and networking, relevant computer hardware, and artificial intelligence.
This work facilitates the cross-use terms from the various contributing sub-areas of information science. With definitions of one-thousand terms, in alphabetical order, the volume provides a unified, integrated, and concise guide to the field. Each term is annotated by one or more references to the literature. Where possible, the first reference directs the user to a basic or seminal discussion of the term and subsequent references show its usage in an information science-related application. This work will be an indispensable reference for students, researchers, and professionals.
Key Features
* Contains one-thousand entries and more than 100 illustrations and tables
* Many entries include enough information (examples, diagrams, and formulas) to allow the reader to make use of the term, model, or algorithm in his or her own application
* An extensive bibliography (more than 300 references) guides the reader to the details of concepts described in the guide--nearly every entry is annotated by one or more references, both to seminal or basic discussions of the concept and to works that demonstrate its usage in an information science-related application
* Each term is followed by a number "key" into the detailed subject outlines at the back of the book, so that each item is given a context within a subject area
* Entries focus on fundamental concepts, rather that specific technologies
