It also defines rules to validate and manipulate this data. It includes representing information with the relational database model, manipulating data with an interactive query language (SQL) and database programming, database development including internet applications, and database security, integrity and privacy issues. ![]() Concepts and Reality in the History of Philosophy: Tracing a Philosophical Error From Locke to Bradley (Routledge Advances in the History of Philosophy) By Fiona Ellis 2005 | 176 Pages | ISBN: 0415334780 | PDF | 2 MB This book traces a deep misunderstanding about the relation of concepts and reality in the history of philosophy. It exposes the influence of the mistake in the thought of Locke, Berkeley, Kant, Nietzche and Bradley, and suggests that the solution can be found in Hegelian thought. Ellis argues that the treatment proposed exemplifies Hegel's dialectical method. This is an important contribution to this area of philosophy. ![]() Concept of Time-Series Database by Ajit Singh English | September 6, 2025 | ISBN: N/A | ASIN: B0FQ3T6SRK | 303 pages | EPUB | 1.95 Mb This book, "Concept of Time-Series Database," is born out of a clear necessity. As educator and professional, I observed a significant gap in academic literature. While countless resources exist for relational and NoSQL databases, a dedicated, student-focused guide that navigates the landscape of time-series databases from foundational principles to advanced, practical implementation was conspicuously absent. This text is my endeavor to fill that void, providing a comprehensive roadmap for the next generation of engineers, developers, and data scientists. ![]() Comte after Positivism (Modern European Philosophy) By Robert C. Scharff 2002 | 248 Pages | ISBN: 0521893038 | PDF | 8 MB This book provides the only detailed, systematic reconsideration of the neglected nineteenth-century positivist Auguste Comte currently available. Apart from offering an accurate account of what Comte actually wrote, the book argues that Comte's positivism has never had greater contemporary relevance than now. Providing a lucid exposition of Comte and informed by considerable new scholarship on his work, this book will be valuable to philosophers, especially philosophers of science, a wide range of intellectual historians, and to historians of science and psychology. ![]() Computing Education Research (Communications in Computer and Information Science) by Prajish Prasad, Arun Raman, Bhumika Shah English | December 17, 2025 | ISBN: 3032145821 | 252 pages | True ePUB, PDF | 28 Mb The 12 full papers and 5 short papers included in this book were carefully reviewed and selected from 79 submissions. They were organized in topical sections as follows: AI and Responsible Computing in Education; Pedagogical Innovations and Interdisciplinary Approaches; Accessibility, Inclusion, and Equity in CS Education; and Tools and Interventions for Core Computing Concepts. ![]() Computing Attitude and Affect in Text: Theory and Applications (The Information Retrieval Series) By James G. Shanahan, Yan Qu, Janyce Wiebe (Editors) 2006 | 357 Pages | ISBN: 1402040261 | PDF | 7 MB The chapters in this book address attitude, affect, and subjective opinion. Various conceptual models and computational methods are presented, including distinguishing attitudes from simple factual assertions; distinguishing between the author's reports from reports of other people's opinions; and distinguishing between explicitly and implicitly stated attitudes. In addition, many applications are described that promise to benefit from the ability to understand attitudes and affect, such as indexing and retrieval of documents by opinion; automatic question answering about opinions; analysis of sentiment in the media and in discussion groups; analyzing client discourse in therapy and counseling; determining relations between scientific texts; generating more appropriate texts; and creating writers' aids. In addition to English texts, the collection includes studies of French, Japanese, and Portuguese texts. The chapters are extended and revised versions of papers presented at the American Association for Artificial Intelligence (AAAI) Spring Symposium on Exploring Attitude and Affect in Text, which took place in March 2004 at Stanford University. The symposium, and the book which grew out it, represent a first foray into this area and a balance among conceptual models, computational methods, and applications. ![]() Computer und IT-Sicherheits-Fibel: Informationen, Tipps und Tricks für Computer-Einsteiger und Fortgeschrittene Deutsch | 13. Juni 2024 | ASIN: B0D73XN1JS | 300 Seiten | Epub | 1.26 MB Bereits veröffentlicht als Computer und IT-Sicherheits-Fibel von Ralf-Peter Kleinert. Aktualisierte Neuauflage. Dieses Buch kann Ihnen eine Hilfe an die Hand geben, wenn es um Computersicherheit geht und wenn es um die Sicherheit Ihrer Informationen geht. Geschrieben habe ich dieses Buch auch für mich selbst, als Nachschlagewerk, Denkanstoß, Erinnerungsauffrischung und als Mahnung, nicht nachzulassen, wenn es um die Sicherheit meiner IT, Computer und Daten geht. Viele Tipps und Anregungen zur Sicherheit in der elektronischen Datenverarbeitung, zur Nutzung Ihrer Computer und Geräte, wie auch Handys, finden sich in dieser Fibel. Wichtige Themen wie Backup und Datensicherung, Passwortsicherheit und die neuen Passkeys, aber auch Gefahren für Ihre Daten im Internet und in den sozialen Medien habe ich thematisiert. Ich gebe Tipps und Vorgehensweisen bei Diebstahl, Erpressung oder Schockanrufen. Außerdem habe ich in den gedruckten Büchern freie Seiten für eigene Notizen eingefügt, die auch im Inhaltsverzeichnis ausgewiesen werden. So können Sie schnell und zielgerichtet auf individuelle Informationen zugreifen, die Sie selbst erstellen können, und haben die wichtigsten Informationen immer zur Hand. Erfahren Sie auch, wie Sie sich gegen Cyber-Mobbing, Hackerangriffe, Phishing und Datenverlust schützen können. Alles in allem habe ich mir viel Mühe gegeben, ein Buch zu verfassen, das individuell auf Leserinnen und Leser eingehen und abgestimmt werden kann. Die Sicherheit Ihrer Daten wie Passwörter, Bankdaten, Versicherungsdaten, Personalien und viele weitere Ihrer wichtigsten sensibelsten Daten stehen im absoluten Vordergrund. Einmal dieses Buch durchgelesen, und schon spüren Sie, dass die Wichtigkeit dieser Themen für Sie selbst nach und nach in den Fokus rutscht. Genau das soll das Buch bewirken. Ich möchte Sie nicht zum Informatiker ausbilden - sondern Sie sensibilisieren und einfache Möglichkeiten eröffnen, wie Sie ihre Daten und sich selbst besser schützen können. Also - bleiben Sie sicher und mit besten Empfehlungen, Ihr Ralf-Peter Kleinert ![]() Daniel Memmert, "Computer Science in Sport: Modeling, Simulation, Data Analysis and Visualization of Sports-Related Data" English | ISBN: 3662683121 | 2024 | 266 pages | MOBI | 5 MB In recent years, computer science in sport has grown extremely, mainly because more and more new data has become available. Computer science tools in sports, whether used for opponent preparation, competition, or scientific analysis, have become indispensable across various levels of expertise nowadays. A completely new market has emerged through the utilization of these tools in the four major fields of application: clubs and associations, business, science, and the media. This market is progressively gaining importance within university research and educational activities. ![]() Daniel Memmert, "Computer Science in Sport: Modeling, Simulation, Data Analysis and Visualization of Sports-Related Data" English | ISBN: 3662683121 | 2024 | 266 pages | AZW3 | 12 MB In recent years, computer science in sport has grown extremely, mainly because more and more new data has become available.

It mentions that computer science (CS) is the foundation of most innovations today, from biotechnology to earth sciences to national security, so it is necessary to include it in schools so that students can acquire relevant skills for the future. The book presents computer science as more than merely using technology. The subject of computer science is very broad and teaches learners design, problem solving and logical reasoning―all of which are valuable outside the computer science classroom. Teachers can use the skills introduced in this book to enable students to design technical solutions to problems in science, mathematics, social studies, art, and humanities.
