Fundamentals of Database Indexing and Searching presents well-known database searching and indexing techniques. It focuses on similarity search queries, showing how to use distance functions to measure the notion of dissimilarity. After defining database queries and similarity search queries, the book organizes the most common and representative index structures according to their characteristics. The author first describes low-dimensional index structures, memory-based index structures, and hierarchical disk-based index structures. He then outlines useful distance measures and index structures that use the distance information to efficiently solve similarity search queries. Focusing on the difficult dimensionality phenomenon, he also presents several indexing methods that specifically deal with high-dimensional spaces. In addition, the book covers data reduction techniques, including embedding, various data transforms, and histograms. Through numerous real-world examples, this book explores how to effectively index and search for information in large collections of data. Requiring only a basic computer science background, it is accessible to practitioners and advanced undergraduate students.

This book provides a comprehensive tutorial on similarity operators. The authors systematically survey the set of similarity operators, primarily focusing on their semantics, while also touching upon mechanisms for processing them effectively. The book starts off by providing introductory material on similarity search systems, highlighting the central role of similarity operators in such systems. This is followed by a systematic categorized overview of the variety of similarity operators that have been proposed in literature over the last two decades, including advanced operators such as RkNN, Reverse k-Ranks, Skyline k-Groups and K-N-Match. Since indexing is a core technology in the practical implementation of similarity operators, various indexing mechanisms are summarized. Finally, current research challenges are outlined, so as to enable interested readers to identify potential directions for future investigations. In summary, this book offers a comprehensive overview of the field of similarity search operators, allowing readers to understand the area of similarity operators as it stands today, and in addition providing them with the background needed to understand recent novel approaches.

Introductory, theory-practice balanced text teaching the fundamentals of databases to advanced undergraduates or graduate students in information systems or computer science.

This edition combines clear explanations of database theory and design with up-to-date coverage of models and real systems. It features excellent examples and access to Addison Wesley's database Web site that includes further teaching, tutorials and many useful student resources.

"Fundamentals of Quantum Data Structures" is a comprehensive guide that introduces the core concepts and principles underlying the marriage of quantum computing and data structures.

With clear explanations and practical examples, the book serves as an invaluable resource for those looking to grasp the fundamentals of organizing and manipulating data in the unique context of quantum computing.

This second edition of Foundations of Nursing Practice has been revised and updated specifically to meet the needs of nursing students in all fields of practice The book explains how and why sensitive, safe, evidence-based holistic nursing care is carried out, including topics common to all fields of practice. Core nursing skills are emphasised to reflect the importance of clinical skills as well as the underpinning theory. Aids to learning in each chapter: - Learning outcomes - Interactive boxes for all age groups and fields of nursing practice - Key words and phrases for literature searching - Useful websites, references and further reading. This book provides a comprehensive introduction to nursing that will meet the needs of students, nurses returning to practice, mentors and other registered nurses. - Relevant to all branches of nursing settings: infants, children, adults, pregnant women, older people and people with a learning disability or mental health problems - Themes relevant to all stages and fields of nursing practice include safety, infection prevention and control, managing stress, communication, managing wounds and pressure ulcers, and dealing with loss - Scenarios develop the skills of evidence-based practice, critical thinking, reflection and health promotion, and encourage further learning - The areas of psychology, sociology, physiology and pathology are clearly related to nursing practice - Key principles of health promotion, the law and ethics, the human lifespan and development are explained in earlier chapters, then applied in later chapters - Cultural diversity information helps with understanding the needs of people from different backgrounds - Person-centred approach encourages problem solving and application to practice - Evidence-based practice is explicit throughout, and best-practice guidelines underpin exploration/explanation of nursing care. - Easy-reference Glossary at the back of the book. - Meets the requirements of the new pre-registration nursing curriculum including the NMC (2010) competencies and Essential Skills Clusters - Greater emphasis on safeguarding vulnerable people, maternal health and first aid - Self-test questions with answers available on accompanying website.
