When you use Hibernate in your projects, you quickly recognize that you need to do more than just add @Entity annotations to your domain model classes. Real-world applications often require advanced mappings, complex queries, custom data types and caching. Hibernate can do all of that. You just have to know which annotations and APIs you need to use. Hibernate Tips - More than 70 solutions to common Hibernate problems shows you how to efficiently implement your persistence layer with Hibernate's basic and advanced features. Each Hibernate Tip consists of one or more code samples and an easy to follow step-by-step explanation. You can also download an example project with executable test cases for each Hibernate Tip. Throughout this book, you will get more than 70 ready-to-use solutions that show you how to: - Define standard mappings for basic attributes and entity associations. - Implement your own attribute mappings and support custom data types. - Use Hibernate's Java 8 support and other proprietary features. - Read data from the database with JPQL, Criteria API, and native SQL queries. - Call stored procedures and database functions. This book is for developers who are already working with Hibernate and who are looking for solutions for their current development tasks. It's not a book for beginners who are looking for extensive descriptions of Hibernate's general concepts. The tips are designed as self-contained recipes which provide a specific solution and can be accessed when needed. Most of them contain links to related tips which you can follow if you want to dive deeper into a topic or need a slightly different solution. There is no need to read the tips in a specific order. Feel free to read the book from cover to cover or to just pick the tips that help you in your current project.

A completely revised edition, offering new design recipes for interactive programs and support for images as plain values, testing, event-driven programming, and even distributed programming. This introduction to programming places computer science at the core of a liberal arts education. Unlike other introductory books, it focuses on the program design process, presenting program design guidelines that show the reader how to analyze a problem statement, how to formulate concise goals, how to make up examples, how to develop an outline of the solution, how to finish the program, and how to test it. Because learning to design programs is about the study of principles and the acquisition of transferable skills, the text does not use an off-the-shelf industrial language but presents a tailor-made teaching language. For the same reason, it offers DrRacket, a programming environment for novices that supports playful, feedback-oriented learning. The environment grows with readers as they master the material in the book until it supports a full-fledged language for the whole spectrum of programming tasks. This second edition has been completely revised. While the book continues to teach a systematic approach to program design, the second edition introduces different design recipes for interactive programs with graphical interfaces and batch programs. It also enriches its design recipes for functions with numerous new hints. Finally, the teaching languages and their IDE now come with support for images as plain values, testing, event-driven programming, and even distributed programming.

Abstraction is a fundamental mechanism underlying both human and artificial perception, representation of knowledge, reasoning and learning. This mechanism plays a crucial role in many disciplines, notably Computer Programming, Natural and Artificial Vision, Complex Systems, Artificial Intelligence and Machine Learning, Art, and Cognitive Sciences. This book first provides the reader with an overview of the notions of abstraction proposed in various disciplines by comparing both commonalities and differences. After discussing the characterizing properties of abstraction, a formal model, the KRA model, is presented to capture them. This model makes the notion of abstraction easily applicable by means of the introduction of a set of abstraction operators and abstraction patterns, reusable across different domains and applications. It is the impact of abstraction in Artificial Intelligence, Complex Systems and Machine Learning which creates the core of the book. A general framework, based on the KRA model, is presented, and its pragmatic power is illustrated with three case studies: Model-based diagnosis, Cartographic Generalization, and learning Hierarchical Hidden Markov Models.

In this stimulating, thought-provoking guide, a noted sculptor and teacher demonstrates how to discover a rich new design source in the abstractions inherent in natural forms. Through systematic study of such properties as line, form, shape, mass, pattern, light and dark, space, proportion, scale, perspective, and color as they appear in nature, students can learn to utilize the infinite variety and diversity of those elements as a wellspring of creative abstraction. The author invites students to learn the necessary techniques through a series of projects devoted to exploring and drawing plants, animals, birds, landscapes, seascapes, skies, and more. Lines of growth and structure, water and liquid forms, weather and atmospheric patterns, luminosity in plants and animals, earth colors and lightning are among the sources of abstraction available to the artist who is aware of them. This book will train you to see and use these elements and many more. An intriguing blend of art, psychology, and the natural sciences, Abstraction in Art and Nature is profusely illustrated with over 370 photographs, scientific illustrations, diagrams, and reproductions of works by the great masters. It not only offers a mind-stretching new way of learning and teaching basic design, but deepens our awareness of the natural environment. In short, Mr. Hale's book is an indispensable guide that artists, teachers, and students will want to have close at hand for instruction, inspiration, and practical guidance.

Architectural form reconsidered in light of a unitary conception of architecture and the city. In The Possibility of an Absolute Architecture, Pier Vittorio Aureli proposes that a sharpened formal consciousness in architecture is a precondition for political, cultural, and social engagement with the city. Aureli uses the term absolute not in the conventional sense of “pure,” but to denote something that is resolutely itself after being separated from its other. In the pursuit of the possibility of an absolute architecture, the other is the space of the city, its extensive organization, and its government. Politics is agonism through separation and confrontation; the very condition of architectural form is to separate and be separated. Through its act of separation and being separated, architecture reveals at once the essence of the city and the essence of itself as political form: the city as the composition of (separate) parts. Aureli revisits the work of four architects whose projects were advanced through the making of architectural form but whose concern was the city at large: Andrea Palladio, Giovanni Battista Piranesi, Étienne Louis-Boullée, and Oswald Mathias Ungers. The work of these architects, Aureli argues, addressed the transformations of the modern city and its urban implications through the elaboration of specific and strategic architectural forms. Their projects for the city do not take the form of an overall plan but are expressed as an “archipelago” of site-specific interventions.

This book investigates Aristotle’s views on abstraction and explores how he uses it. In this work, the author follows Aristotle in focusing on the scientific detail first and then approaches the metaphysical claims, and so creates a reconstructed theory that explains many puzzles of Aristotle’s thought. Understanding the details of his theory of relations and abstraction further illuminates his theory of universals. Some of the features of Aristotle’s theory of abstraction developed in this book include: abstraction is a relation; perception and knowledge are types of abstraction; the objects generated by abstractions are relata which can serve as subjects in their own right, whereupon they can appear as items in other categories. The author goes on to look at how Aristotle distinguishes the concrete from the abstract paronym, how induction is a type of abstraction which typically moves from the perceived individuals to universals and how Aristotle’s metaphysical vocabulary is "relational.’ Beyond those features, this work also looks at how of universals, accidents, forms, causes and potentialities have being only as abstract aspects of individual substances. An individual substance is identical to its essence; the essence has universal features but is the singularity making the individual substance what it is. These theories are expounded within this book. One main attraction in working out the details of Aristotle’s views on abstraction lies in understanding his metaphysics of universals as abstract objects. This work reclaims past ground as the main philosophical tradition of abstraction has been ignored in recent times. It gives a modern version of the medieval doctrine of the threefold distinction of essence, made famous by the Islamic philosopher, Avicenna.

This book explores the development of abstraction from the moment of its declaration around 1912 to its establishment as the foundation of avant-garde practice in the mid-1920s. The book brings together many of the most influential works in abstractions early history to draw a cross-media portrait of this watershed moment in which traditional art was reinvented in a wholesale way. Works are presented in groups that serve as case studies, each engaging a key topic in abstractions first years: an artist, a movement, an exhibition or thematic concern. Key focal points include Vasily Kandinskys ambitious Compositions V, VI and VII; a selection of Piet Mondrians work that offers a distilled narrative of his trajectory to Neo-plasticism; and all the extant Suprematist pictures that Kazimir Malevich showed in the landmark 0.10 exhibition in 1915.0Exhibition: MoMA, New York, USA (23.12.2012-15.4.2013).

This book uncovers how we make meaning of abstraction, both historically and in present times, and examines abstract images as a visual language. The contributors demonstrate that abstraction is not primarily an artistic phenomenon, but rather arises from human beings’ desire to imagine, understand and communicate complex, ineffable concepts in fields ranging from fine art and philosophy to technologies of data visualization, from cartography and medicine to astronomy. The book will be of interest to scholars working in image studies, visual studies, art history, philosophy and aesthetics.

Liskov (engineering, Massachusetts Institute of Technology) and Guttag (computer science and engineering, also at MIT) present a component- based methodology for software program development. The book focuses on modular program construction: how to get the modules right and how to organize a program as a collection of modules. It explains the key types of abstractions, demonstrates how to develop specifications that define these abstractions, and illustrates how to implement them using numerous examples. An introduction to key Java concepts is included. Annotation copyrighted by Book News, Inc., Portland, OR.

An approach to software design that introduces a fully automated analysis giving designers immediate feedback, now featuring the latest version of the Alloy language. In Software Abstractions Daniel Jackson introduces an approach to software design that draws on traditional formal methods but exploits automated tools to find flaws as early as possible. This approach—which Jackson calls “lightweight formal methods” or “agile modeling”—takes from formal specification the idea of a precise and expressive notation based on a tiny core of simple and robust concepts but replaces conventional analysis based on theorem proving with a fully automated analysis that gives designers immediate feedback. Jackson has developed Alloy, a language that captures the essence of software abstractions simply and succinctly, using a minimal toolkit of mathematical notions. This revised edition updates the text, examples, and appendixes to be fully compatible with Alloy 4.
