This nuts-and-bolts guide shows you the power of XML by presenting an enterprise application problem that you´ll design a program to solve throughout the book. Each chapter takes one part of the featured project and leads you through the design of its solution. The team of experienced authors gradually walks you through sections of increasing depth, each one developing a more advanced treatment of XML than the previous. You´ll learn various resolutions to common business and technology needs that are best solved using XML. Plus, you´ll get under the hood of everyday applications and web services and discover how to tackle XML markup. By the end of the book, you will understand how to leverage XML applications in order to build a complete, functional, end-to-end XML solution. What you will learn from this book * How to share XML data with both internal and external users * Ways to style XML so that it can be used for browser presentation * Techniques for converting XML content online using XSLT, the XML transformation language * How to search, merge, and transform XML documents * Strategies for designing enterprise solutions using XML, workflow engines, and business process management systems * How to create PDF output and produce RSS feeds Who this book is for This book is for programmers new to XML who want to grasp the concepts of XML markup and understand the diversity of its potential uses. Wrox Problem - Design - Solution gives you solid, workable solutions to real-world development problems. Each chapter is devoted to a single application, analyzing every problem, examining relevant design issues, and implementing the ideal solution.

Relational and XML Data Exchange
29,00 € *
ggf. zzgl. Versand

Data exchange is the problem of finding an instance of a target schema, given an instance of a source schema and a specification of the relationship between the source and the target. Such a target instance should correctly represent information from the source instance under the constraints imposed by the target schema, and it should allow one to evaluate queries on the target instance in a way that is semantically consistent with the source data. Data exchange is an old problem that re-emerged as an active research topic recently, due to the increased need for exchange of data in various formats, often in e-business applications. In this lecture, we give an overview of the basic concepts of data exchange in both relational and XML contexts. We give examples of data exchange problems, and we introduce the main tasks that need to addressed. We then discuss relational data exchange, concentrating on issues such as relational schema mappings, materializing target instances (including canonical solutions and cores), query answering, and query rewriting. After that, we discuss metadata management, i.e., handling schema mappings themselves. We pay particular attention to operations on schema mappings, such as composition and inverse. Finally, we describe both data exchange and metadata management in the context of XML. We use mappings based on transforming tree patterns, and we show that they lead to a host of new problems that did not arise in the relational case, but they need to be addressed for XML. These include consistency issues for mappings and schemas, as well as imposing tighter restrictions on mappings and queries to achieve tractable query answering in data exchange.

Transactions on Large-Scale Data- and Knowledge...
67,40 € *
ggf. zzgl. Versand

The LNCS journal Transactions on Large-Scale Data- and Knowledge-Centered Systems focuses on data management, knowledge discovery, and knowledge processing, which are core and hot topics in computer science. Since the 1990s, the Internet has become the main driving force behind application development in all domains. An increase in the demand for resource sharing across different sites connected through networks has led to an evolution of data- and knowledge-management systems from centralized systems to decentralized systems enabling large-scale distributed applications providing high scalability. Current decentralized systems still focus on data and knowledge as their main resource. Feasibility of these systems relies basically on P2P (peer-to-peer) techniques and the support of agent systems with scaling and decentralized control. Synergy between grids, P2P systems, and agent technologies is the key to data-and knowledge-centered systems in large-scale environments. This, the 10th issue of Transactions on Large-Scale Data- and Knowledge-Centered Systems, contains seven full papers chosen following two additional rounds of reviewing from revised and extended versions of a selection of papers presented at DEXA 2012. Topics covered include formal modelling and verification of web services, incremental computation of skyline queries, the implication problem for XML keys, lossless data compression, declarative view selection methods, time awareness in recommender systems, and network data mining.

Effective device management
49,00 € *
ggf. zzgl. Versand

The main problem with device management is to efficiently manage devices with different capabilities and modes of usage operating in networks of various sizes. There is no unified solution to manage all types of devices working in all types of networks. Instead, many small projects are developed simultaneously forcing administrators to use several types of software. Usually, each hardware vendor creates custom software for device management. This solution generates additional costs of different kinds: the need for additional hardware, software and human power to operate it as well as the cost of knowledge required to use the software and the typically hidden and rarely calculated cost of degraded quality of service. The problem of choosing the appropriate device management solution, analysing it and performing optimizations is not trivial. This book describes Open Mobile Alliance Device Management solutions and investigates how to use them in the most efficient way.

The commercial success of cellular networks, combined with advances in digital electronics, signal processing, and computer and telecommunications research have lead to deliver the same level of Information technology service to a Mobile Devices ´´anywhere at anytime´´. So new demand called Mobile business introduced world wide. The system enables the presentation of Web content and considers the problem of small screen display of mobile computing devices. Also independent-device access to web content is considered. The focus has mainly been on the adaptation of HTML web page content to make it viewable on mobile devices, constraint that no server-side content adjustments are assumed. The adaptation is done by using the re-authoring syntactic elision and syntactic transformation techniques started by parsing the HTML web page and converting it to tree structure.
