The W3C XQuery 3.1 standard provides a tool to search, extract, and manipulate content, whether it´s in XML, JSON or plain text. With this fully updated, in-depth tutorial, youll learn to program with this highly practical query language.Designed for query writers who have some knowledge of XML basics, but not necessarily advanced knowledge of XML-related technologies, this book is ideal as both a tutorial and a reference. Youll find background information for namespaces, schemas, built-in types, and regular expressions that are relevant to writing XML queries.This second edition provides:A high-level overview and quick tour of XQueryNew chapters on higher-order functions, maps, arrays, and JSONA carefully paced tutorial that teaches XQuery without being bogged down by the detailsAdvanced concepts for taking advantage of modularity, namespaces, typing, and schemasGuidelines for working with specific types of data, such as numbers, strings, dates, URIs, maps and arraysXQuerys implementation-specific features and its relationship to other standards including SQL and XSLTA complete alphabetical reference to the built-in functions, types, and error messages
The topic of using views to answer queries has been popular for a few decades now, as it cuts across domains such as query optimization, information integration, data warehousing, website design and, recently, database-as-a-service and data placement in cloud systems. This book assembles foundational work on answering queries using views in a self-contained manner, with an effort to choose material that constitutes the backbone of the research. It presents efficient algorithms and covers the following problems: query containment; rewriting queries using views in various logical languages; equivalent rewritings and maximally contained rewritings; and computing certain answers in the data-integration and data-exchange settings. Query languages that are considered are fragments of SQL, in particular select-project-join queries, also called conjunctive queries (with or without arithmetic comparisons or negation), and aggregate SQL queries. This second edition includes two new chapters that refer to tree-like data and respective query languages. Chapter 8 presents the data model for XML documents and the XPath query language, and Chapter 9 provides a theoretical presentation of tree-like data model and query language where the tuples of a relation share a tree-structured schema for that relation and the query language is a dialect of SQL with evaluation techniques appropriately modified to fit the richer schema.
Welcome to Hollywood! Follow the saga of the Acme Pictures movie studio as it exchanges information with its vendor and its primary customer to put low-budget sci-fi movies on shelves. This entertaining case study showcases the requirements, standards, and capabilities for building an SAP EDI system and optimizing electronic information exchange via IDocs. From configuring IDocs, to generating purchase orders and goods receipts, to processing invoices, this script teaches you how to make your EDI system a star. 1. Cross-Industry Standard See what makes IDocs in SAP and EDI the heart, bones, arteries, and brains of modern businesses and government organizations. 2. The Full Picture Build the EDI system step by step, from generating the purchase order, to building outbound order confirmation, to processing the inbound payment advice using IDocs. 3. Custom IDocs Using ABAP, ALE, and XML, explore custom utilities that extend standard SAP functionality. 4. Test Your System Learn how to achieve success and diagnose failure by using monitoring tools to troubleshoot. 5. Updated and Expanded In this second edition, find new custom tools and utilities, a renewed focus on the business context, and new interfaces from the purchasing cycle. Highlights include: Business process integration IDoc architecture and configuration Custom IDocs and extensions Mapping specifications Message control Customer purchase orders Replication services Inbound goods receipts and invoices Outbound advance shipments and invoices Custom IDoc tools EDI and IDocs troubleshooting and recovery
The Eclpise Modeling Framework (EMF) is a framework and code generation facility that lets you define a model in any of these forms--Java interfaces, UML diagram, or XML Schema. EMF doesn´t require a completely different methodology or any sophisticated modeling tools. All you need to get started with EMF are the Eclipse Java Development Tools. EMF relates modeling concepts directly to their implementations, thereby bringing to Eclipse-and Java developers in general-the benefits of modeling with a low cost of entry. Unlike most tools of this type, EMF is truly integrated with and tuned for efficient programming. It answers the often-asked question, ´´Should I model or should I program?´´ with a resounding, ´´Both.´´ This book, written by the lead architects of EMF, provides both an introduction and tutorial to how to leverage and work with this powerful framework. In addition to the new coverage (see overflow page) this book provides: · A basic overview of the most important concepts in EMF and modeling. · Analysis of the most important framework classes and generator patterns including insightful discussions of various design alternatives. · Examples of many common framework customizations and programming techniques. Product Description EMF: Eclipse Modeling Framework Dave Steinberg Frank Budinsky Marcelo Paternostro Ed Merks Series Editors: Erich Gamma . Lee Nackman . John Wiegand The Authoritative Guide to EMF Modeling and Code Generation The Eclipse Modeling Framework enables developers to rapidly construct robust applications based on surprisingly simple models. Now, in this thoroughly revised Second Edition, the project´s developers offer expert guidance, insight, and examples for solving real-world problems with EMF, accelerating development processes, and improving software quality. This edition contains more than 40% new material, plus updates throughout to make it even more useful and practical. The authors illuminate the key concepts and techniques of EMF modeling, analyze EMF´s most important framework classes and generator patterns, guide you through choosing optimal designs, and introduce powerful framework customizations and programming techniques. Coverage includes . Defining models with Java, UML, XML Schema, and Ecore . NEW: Using extended Ecore modeling to fully unify XML with UML and Java . Generating high-quality code to implement models and editors . Understanding and customizing generated code . Complete documentation of @model Javadoc tags, generator model properties, and resource save and load options . NEW: Leveraging the latest EMF features, including extended metadata, feature maps, EStore, cross-reference adapters, copiers, and content types . NEW: Chapters on change recording, validation, and utilizing EMF in stand-alone and Eclipse RCP applications . NEW: Modeling generics with Ecore and generating Java 5 code About the Authors Dave Steinberg is a software developer in IBM Software Group. He has worked with Eclipse and modeling technologies since joining the company, and has been a committer on the EMF project since its debut in 2002. Frank Budinsky, a senior architect in IBM Software Group, is an original coinventor of EMF and a founding member of the EMF project at Eclipse. He is currently cochair of the Service Data Objects (SDO) specification technical committee at OASIS and lead SDO architect for IBM. Marcelo Paternostro is a software architect and engineer in IBM Software Group. He is an EMF committer and has been an active contributor to several other Eclipse projects. Before joining IBM, Marcelo managed, designed, and implemented numerous projects using Rational´s tools and processes. Ed Merks is the project lead of EMF and a colead of the top-level Modeling project at Eclipse. He holds a Ph.D. in Computing Science and has many years of in-depth experience in the design and implementation of languages, frameworks, and application development environments. Ed works as a software consultant in partnership with itemis AG. Backcover EMF: Eclipse Modeling Framework Dave Steinberg Frank Budinsky Marcelo Paternostro Ed Merks Series Editors: Erich Gamma .
