Database System Concepts by Silberschatz, Korth and Sudarshan is now in its 7th edition and is one of the cornerstone texts of database education. It presents the fundamental concepts of database management in an intuitive manner geared toward allowing students to begin working with databases as quickly as possible. The text is designed for a first course in databases at the junior/senior undergraduate level or the first year graduate level. It also contains additional material that can be used as supplements or as introductory material for an advanced course. Because the authors present concepts as intuitive descriptions, a familiarity with basic data structures, computer organization, and a high-level programming language are the only prerequisites. Important theoretical results are covered, but formal proofs are omitted. In place of proofs, figures and examples are used to suggest why a result is true.

Cet ouvrage est une édition plus approfondie du livre du même auteur "Modélisation Conceptuelle de Données - Une Démarche Pragmatique" dont il reprend la structure et la démarche pédagogique permettant de réaliser des modèles conceptuels de données sans faire appel à de quelconques connaissances préalables, et en limitant les aspects théoriques à leur strict minimum. Les modèles de données, essentiellement mis en œuvre avec le formalisme entité-association, mais également avec des diagrammes de classes UML, font ensuite l'objet d'une étude poussée pour permettre une génération SQL précise et optimale du schéma relationnel des bases de données correspondantes, des plus simples aux plus complexes. Une approche concrète et pratique est privilégiée avec, en support, de nombreux schémas, illustrations et exercices corrigés. Ce livre s'adresse aux étudiants de BUT, BTS, licences, masters, écoles d'ingénieurs, classes préparatoires, à leurs professeurs, ainsi qu'à tous les professionnels désireux de concevoir des bases de données de manière précise et rigoureuse.

Ce livre de cours traduit de l'américain, sans équivalent et d'accès facile, est une introduction complète à l'algorithmique et s'adresse aussi bien aux étudiants qu'aux professionnels en informatique. L'éventail des algorithmes étudiés va des plus classiques (tris, hachage...) aux plus récents (algorithmes parallèles...) permettant ainsi de passer progressivement des notions élémentaires aux thèmes les plus pointus. Les algorithmes sont présentés dans un pseudo-code proche des langages Pascal, C et Fortran, ce qui les rend très faciles à comprendre et à implémenter. Ils sont complétés par des preuves mathématiques et illustrés par de nombreux exemples. Au total, plus de 920 exercices et 140 problèmes sont proposés. Sommaire :Bases mathématiques; Tri et rangs; Structures de données; Techniques avancées de conception et d'analyse; Structures de données avancées; Algorithmes sur les graphes; Morceaux choisis.

Everyone knows that programming plays a vital role as a solution to automate and execute a task in a proper manner. Irrespective of mathematical problems, the skills of programming are necessary to solve any type of problems that may be correlated to solve real life problems efficiently and effectively. This book is intended to flow from the basic concepts of C++ to technicalities of the programming language, its approach and debugging. The chapters of the book flow with the formulation of the problem, it's designing, finding the step-by-step solution procedure along with its compilation, debugging and execution with the output. Keeping in mind the learner’s sentiments and requirements, the exemplary programs are narrated with a simple approach so that it can lead to creation of good programs that not only executes properly to give the output, but also enables the learners to incorporate programming skills in them.

Strengthen your understanding of data structures and their algorithms for the foundation you need to successfully design, implement and maintain virtually any software system. Theoretical, yet practical, DATA STRUCUTRES AND ALGORITHMS IN C++, 4E by experienced author Adam Drosdek highlights the fundamental connection between data structures and their algorithms, giving equal weight to the practical implementation of data structures and the theoretical analysis of algorithms and their efficiency. This edition provides critical new coverage of treaps, k-d trees and k-d B-trees, generational garbage collection, and other advanced topics such as sorting methods and a new hashing technique. Abundant C++ code examples and a variety of case studies provide valuable insights into data structures implementation. DATA STRUCTURES AND ALGORITHMS IN C++ provides the balance of theory and practice to prepare readers for a variety of applications in a modern, object-oriented paradigm.

"Data Structure and Algorithmic Thinking with Python" is designed to give a jump-start to programmers, job hunters and those who are appearing for exams. All the code in this book are written in Python. It contains many programming puzzles that not only encourage analytical thinking, but also prepares readers for interviews. This book, with its focused and practical approach, can help readers quickly pick up the concepts and techniques for developing efficient and effective solutions to problems.

The style of writing a program using a programming language is also emphasized by introducing the inclusion of comments wherever necessary to encourage writing more readable and well commented programs. As practice makes perfect, each chapter is also enriched with practice exercise questions so as to build the confidence of writing the programs for learners. The book is a complete and all-inclusive handbook of C++ that covers all that a learner as a beginner would expect, as well as complete enough to go ahead with advanced programming. This book will provide a fundamental idea about the concepts of data structures and associated algorithms. By going through the book, the reader will be able to understand about the different types of algorithms and at which situation and what type of algorithms will be applicable.
