Neo4j est un système de gestion de bases de données NoSQL orientées graphe, particulièrement adapté à des situations où les données sont fortement connectées et structurées selon des modèles complexes et évolutifs. À la différence des systèmes classiques, son approche n'est pas fondée sur l'algèbre relationnelle mais sur la théorie des graphes. Il permet ainsi de trouver de manière très performante des données reliées entre elles selon une profondeur non connue à l’avance. Ce livre vous permettra de prendre connaissance avec l'approche graphe de Neo4j et d'en mesurer le potentiel. Il vous fournira tous les outils pour pouvoir le tester aussi bien en local que sur un serveur distant. Vous apprendrez à l'aide d'exemples concrets à manipuler les données avec son langage d'interrogation CYPHER et via son API REST. Il s'adresse à tous les développeurs, responsables de projets, architectes logiciels en quête d'une alternative aux systèmes de bases de données relationnelles classiques. Il ne requiert aucune compétence particulière en matière de théorie des graphes. En revanche, une connaissance des bases de données traditionnelles aidera à mieux cerner les problématiques auxquelles répond Neo4j. Cette deuxième édition a été enrichie d'un nouveau chapitre portant sur les graphgists et l'analyse d'un cas d'utilisation. Son code a été entièrement révisé pour être compatible avec la version 3.0. et différents points ont été complétés pour intégrer les multiples changements apparus depuis la version 2.0 de Neo4j.

Vous avez déjà une idée de ce qu'est Neo4j et de son mode de fonctionnement, peut-être même avez-vous déjà fait quelques tests. La question maintenant est de savoir comment le mettre en œuvre dans un contexte de production. C'est ce que vous explique ce livre. Conçu sous la forme originale d'un dialogue entre les différents membres d'une équipe technique spécialisée dans la manipulation de données fortement connectées, il s'efforce de répondre à toutes les questions qu'on peut se poser lors de la mise en place d'un projet, de la preuve de concept jusqu'à la maintenance et la sécurisation. Des annexes, ainsi que de multiples encadrés au fil du récit viennent compléter certains aspects techniques. Vous y apprendrez : ・ à analyser un problème en termes de graphe ・ à intégrer Neo4j dans un système déjà existant et interagir avec d'autres bases de données ・ à importer ou exporter des données ・ à garantir la disponibilité et la sécurité des données ・ à surveiller et maintenir Neo4j Si vous débutez avec Neo4j, nous vous recommandons de commencer par le volume I. Prise en main. "C'est sous forme théâtrale que j'ai choisi de relater le déploiement de Neo4j, car n'est-ce pas finalement ce à quoi ressemble notre vie professionnelle ? Un petit théâtre." - Sylvain Roussy "Le futur de Neo4j est plein d'innovation et de possibilités : Mervaillie, Roussy et Rouyer ont écrit un ouvrage abouti qui vous aidera à en tirer tout le potentiel." - Jim Webber, Chief Scientist de Neo4j, Inc.

Database Design is the book you need to master the fundamentals of relational database design in today's ever-evolving world of database technologies. This book takes an approach to database design to teach the reader how to reach into the inner depths of an organization to understand the business needs, data, and daily processes that will all blend together to formulate a successful database. Much emphasis is placed on logical design as it is imperative to understand the inner workings of an organization to produce the highest quality database, while proactively eliminating future problems that are not so easy for a beginner to foresee. Additionally, topics such as change control, business rule integration, database security implementation, and legacy database redesign are covered in detail. Examples of SQL code are shown to portray implementation tasks of a relational database. Examples are compliant with ANSI standard.

The need to handle increasingly larger data volumes is one factor driving the adoption of a new class of nonrelational “NoSQL” databases. Advocates of NoSQL databases claim they can be used to build systems that are more performant, scale better, and are easier to program. NoSQL Distilled is a concise but thorough introduction to this rapidly emerging technology. Pramod J. Sadalage and Martin Fowler explain how NoSQL databases work and the ways that they may be a superior alternative to a traditional RDBMS. The authors provide a fast-paced guide to the concepts you need to know in order to evaluate whether NoSQL databases are right for your needs and, if so, which technologies you should explore further. The first part of the book concentrates on core concepts, including schemaless data models, aggregates, new distribution models, the CAP theorem, and map-reduce. In the second part, the authors explore architectural and design issues associated with implementing NoSQL. They also present realistic use cases that demonstrate NoSQL databases at work and feature representative examples using Riak, MongoDB, Cassandra, and Neo4j. In addition, by drawing on Pramod Sadalage's pioneering work, NoSQL Distilled shows how to implement evolutionary design with schema migration: an essential technique for applying NoSQL databases. The book concludes by describing how NoSQL is ushering in a new age of Polyglot Persistence, where multiple data-storage worlds coexist, and architects can choose the technology best optimized for each type of data access.
