From object technology pioneer and ETH Zurich professor Bertrand Meyer, winner of the Jolt award and the ACM Software System Award, a revolutionary textbook that makes learning programming fun and rewarding. Meyer builds his presentation on a rich object-oriented software system supporting graphics and multimedia, which students can use to produce impressive applications from day one, then understand inside out as they learn new programming techniques. Unique to Touch of Class is a combination of a practical, hands-on approach to programming with the introduction of sound theoretical support focused on helping students learn the construction of high quality software. The use of full color brings exciting programming concepts to life. Among the useful features of the book is the use of Design by Contract, critical to software quality and providing a gentle introduction to formal methods. Will give students a major advantage by teaching professional-level techniques in a literate, relaxed and humorous way.
Thinking of migrating to PostgreSQL? This clear, fast-paced introduction helps you understand and use this open source database system. Not only will you learn about the enterprise class features in versions 9.5 to 10, you´ll also discover that PostgeSQL is more than a database system-it´s an impressive application platform as well.
Class-tested and coherent, this textbook teaches information retrieval, including web search, text classification, and text clustering from basic concepts. Ideas are explained using examples and figures, making it perfect for introductory courses in information retrieval for advanced undergraduates and graduate students. Slides and additional exercises are available for lecturers.
Write code that writes code with Elixir macros. Macros make metaprogramming possible and define the language itself. In this book, you´ll learn how to use macros to extend the language with fast, maintainable code and share functionality in ways you never thought possible. You´ll discover how to extend Elixir with your own first-class features, optimize performance, and create domain-specific languages.
This is the missing X Window book. While others have shown what the X Window system has available, this book shows how to convert this potential into working tools to fulfil your visualisation needs. It is of the show-me class of books. The majority of the book covers Xlib, although a short coverage of Xcb is also given. Included are: . The relationship between Xlib and the X Window protocol; . All the basic Xlib topics are covered; . Complete working programs with their results; . Exercises to reinforce the material just covered. A 9 part partition to building a complete X program is used throughout. This partitioning fosters the inclusion of all code necessary. All programs are written in C and are one to four pages in length. Open source programs with the occasional Postscript script are shown to provide support as needed. Throughout the examples consideration is given to using colour. The examples produce simple results with the aim of providing building blocks for application oriented codes. The book is directed at graduate students and researchers who create computer code to visualise their data.
A basic issue in computer science is the complexity of problems. Computational complexity measures how much time or memory is needed as a function of the input problem size. Descriptive complexity is concerned with problems which may be described in first-order logic. By virtue of the close relationship between logic and relational databses, it turns out that this subject has important applications to databases such as analysing the queries computable in polynomial time, analysing the parallel time needed to compute a query, and the analysis of nondeterministic classes. This book is written as a graduate text and so aims to provide a reasonably self-contained introduction to this subject. The author has provided numerous examples and exercises to further illustrate the ideas presented.
For years, Thomas Erl´s Service-Oriented Architecture: Concepts, Technology, and Design has been the definitive end-to-end tutorial on SOA, service orientation, and service technologies. Now, Erl and a world-class team of service experts have thoroughly updated their best-seller to reflect the new practices, technologies, and strategies that have emerged through the past decade of hard-won SOA experience. Fully reflective of modern SOA environments, this Second Edition presents dozens of current case study examples, as well as 300+ diagrams that illuminate every key facet of creating, leveraging, and sustaining contemporary SOA. Erl and his colleagues guide you through every key phase of the SOA delivery lifecycle, from analysis and design through modern governance. Coverage includes: * How SOA has evolved: crucial lessons learned, and current best practices * Service technologies: WS-* and REST in contemporary environments * Service Orientation principles and techniques, including new approaches to Service Inventories * Building SOA: planning, analysis, modeling, technology, and design * Governing SOA, including new SOA Governance Frameworks and Vitality approaches
The DbContext API captures Entity Framework?s (EF) most commonly used features and tasks, simplifying development with EF. This concise book shows you how to use the API to perform set operations with the DbSet class, handle change tracking and resolve concurrency conflicts with the Change Tracker API, and validate changes to your data with the Validation API. With DbContext, you?ll be able to query and update data, whether you?re working with individual objects or graphs of objects and their related data. You?ll find numerous C# code samples to help you get started. All you need is experience with Visual Studio and database management basics. * Use EF?s query capabilities to retrieve data, and use LINQ to sort and filter data * Learn how to add new data, and change and delete existing data * Use the Change Tracker API to access information EF keeps about the state of entity instances * Control change tracking information of entities in disconnected scenarios, including NTier applications * Validate data changes before they?re sent to the database, and set up validation rules * Bypass EF?s query pipeline and interact directly with the database
Why don´t typical enterprise projects go as smoothly as projects you develop for the Web? Does the REST architectural style really present a viable alternative for building distributed systems and enterprise-class applications? In this insightful book, three SOA experts provide a down-to-earth explanation of REST and demonstrate how you can develop simple and elegant distributed hypermedia systems by applying the Web´s guiding principles to common enterprise computing problems. You´ll learn techniques for implementing specific Web technologies and patterns to solve the needs of a typical company as it grows from modest beginnings to become a global enterprise. * Learn basic Web techniques for application integration * Use HTTP and the Web?s infrastructure to build scalable, fault-tolerant enterprise applications * Discover the Create, Read, Update, Delete (CRUD) pattern for manipulating resources * Build RESTful services that use hypermedia to model state transitions and describe business protocols * Learn how to make Web-based solutions secure and interoperable * Extend integration patterns for event-driven computing with the Atom Syndication Format and implement multi-party interactions in AtomPub * Understand how the Semantic Web will impact systems design
