This book was released on 2013-04-01 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Le développement spectaculaire d’internet, des réseaux sociaux, de la technologie mobile et la multiplication des capteurs provoquent une croissance exponentielle des données à laquelle les entreprises doivent faire face : c’est le phénomène du Big Data. Ses enjeux sont considérables. Au-delà de la simple question technique du stockage, il offre la possibilité de tirer profit du contenu de ces nouvelles sources d’information. Les solutions décisionnelles classiques laissent progressivement place au Business Analytics et aux méthodes prédictives, transformant l’avalanche de données en valeur ajoutée. La technologie est aujourd’hui disponible, les bases de données traditionnelles ont évolué et les solutions dédiées à l’exploitation des données massives, telles que Hadoop, sont désormais opérationnelles. S’appuyant sur différents cas pratiques, Enjeux et usages du Big Data met l’accent sur les méthodes, les techniques et les ressources nécessaires pour permettre aux entreprises d’entrer avec succès dans l’ère de l’information à grande échelle.

This book was released on 2023-01-13 with total page 727 pages. Available in PDF, EPUB and Kindle. Book excerpt: Le Manuel de référence sur les systèmes de mise en œuvre de la protection sociale synthétise les expériences et les leçons apprises des systèmes de mise en œuvre de la protection sociale à travers le monde. Il adopte un concept de la protection sociale large, qui couvre différentes populations telles que les familles pauvres ou à faible revenu, les chômeurs, les personnes handicapées et les personnes confrontées à des risques sociaux. Il analyse différents types d’interventions des gouvernements pour la protection des individus, des familles ou des ménages, au travers de programmes spécifiques allant de programmes ciblant la pauvreté, aux prestations et services en faveur de l’emploi, et aux prestations et services au bénéfice des personnes handicapées et d’autres services sociaux. Ce Manuel de référence cherche à répondre à différentes questions pratiques soulevées au cours de la mise en œuvre, en particulier : • Comment les pays mettent-ils en œuvre les prestations et services de protection sociale ? • Comment le font-ils avec l’efficacité et l’efficience voulues ? • Comment assurent-ils une inclusion dynamique, en particulier celle des personnes les plus vulnérables et les plus défavorisées ? • Comment favorisent-ils une meilleure coordination et intégration non seulement entre les différents programmes de protection sociale mais aussi avec les programmes mis en œuvre par d’autres acteurs gouvernementaux ? • Comment peuvent-ils répondre aux besoins des populations ciblées et assurer une meilleure expérience client ? Le cadre de mise en œuvre des systèmes de protection sociale précise les principaux éléments de cet environnement opérationnel. Il se décline en différentes phases qui s’échelonnent tout au long de la chaîne de mise en oeuvre. Ces phases sont les lieux d’interactions entre différents acteurs, parmi lesquels des personnes et des institutions. La communication, les systèmes d’information et la technologie facilitent ces interactions. Ce cadre peut s’appliquer à la mise en œuvre d’un ou plusieurs programmes ainsi qu’à la mise en place d’une protection sociale adaptative. Le Manuel de référence des systèmes de mise en œuvre de la protection sociale s’articule autour de huit principes clés qui constituent le code de conduite de la mise en œuvre : 1. Les systèmes de mise en œuvre ne suivent pas un modèle unique, mais tous les modèles partagent des points communs qui forment le coeur du cadre de mise en œuvre des systèmes de protection sociale. 2. La qualité de la mise en œuvre a une grande importance et la faiblesse de l’un des éléments constitutifs de la chaîne de mise en œuvre affectera négativement l’ensemble de celle-ci et réduira les impacts du ou des programmes qui lui sont associés. 3. Les systèmes de mise en œuvre évoluent dans le temps, de manière non linéaire et leur point de départ est important. 4. Dès le début de la mise en œuvre, des efforts devront être déployés pour « garder les choses simples » et pour « bien faire les choses simples ». 5. Le premier segment de la chaîne, à savoir l’interface entre les futurs bénéficiaires et l’administration, est souvent son maillon le plus faible. Son amélioration peut nécessiter des changements systémiques, mais ceux-ci contribueront considérablement à l’efficacité globale et atténueront les risques d’échec de cette interface. 6. Les programmes de protection sociale ne fonctionnent pas dans le vide et, par conséquent, leur système de mise en œuvre ne doit pas être développé en vase clos. Des opportunités de synergies entre institutions et systèmes d’information existent et les saisir peut améliorer les résultats des programmes. 7. Au-delà de la protection sociale, ces systèmes de mise en œuvre peuvent aussi améliorer la capacité des gouvernements à fournir d’autres prestations ou services, comme les subventions à l’assurance maladie, les bourses d’études, les tarifs sociaux de l’énergie, les allocations logement et l’accès aux services juridiques. 8. L’inclusion et la coordination sont des défis omniprésents et permanents. Pour les relever, il faut donc améliorer de façon continue les systèmes de mise en œuvre à travers une approche dynamique, intégrée et centrée sur la personne.

Download or read book How to Make a Database in Historical Studies written by Tiago Luís Gil and published by Springer Nature. This book was released on 2021-07-27 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a greatly supplemented translation from Portuguese, originally published in 2015. It discusses the most appropriate ways to create databases for research on history and other humanities, including an extensive debate about the usages that historians have made of computing since the 1950s. It has four chapters: the first is dedicated to theoretical and methodical questions about the usage of databases in history; the second is about technical issues; the third presents the concept of research engineering (how to improve research in groups); the last is about the construction of databases. The author states that the use of technology in research in history and humanities should be preceded and mediated by theories and methods which deal with these disciplines and not by technical issues. The historian must know how to think “correctly” in order to use the technological tools in an autonomous way. The book provides a background, demonstrating how theory, methodology, and technique are always articulated in historical research, and will appeal to history students and researchers.

Download or read book Geographic Data Imperfection 1 written by Mireille Batton-Hubert and published by John Wiley & Sons. This book was released on 2019-09-11 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geomatics is a field of science that has been intimately intertwined with our daily lives for almost 30 years, to the point where we often forget all the challenges it entails. Who does not have a navigation application on their phone or regularly engage with geolocated data? What is more, in the coming decades, the accumulation of geo-referenced data is expected to increase significantly. This book focuses on the notion of the imperfection of geographic data, an important topic in geomatics. It is essential to be able to define and represent the imperfections that are encountered in geographical data. Ignoring these imperfections can lead to many risks, for example in the use of maps which may be rendered inaccurate. It is, therefore, essential to know how to model and treat the different categories of imperfection. A better awareness of these imperfections will improve the analysis and the use of this type of data.

Available in PDF, EPUB and Kindle. Book excerpt: Des bases pour la performance et le Big Data En quelques années, le volume des données brassées par les entreprises a considérablement augmenté. Émanant de sources diverses (transactions, comportements, réseaux sociaux, géolocalisation...), elles sont souvent structurées autour d'un seul point d'entrée, la clé, et susceptibles de croître très rapidement. Autant de caractéristiques qui les rendent très difficiles à traiter avec des outils classiques de gestion de données. Par ailleurs, l'analyse de grands volumes de données, ce qu'on appelle le Big Data, défie également les moteurs de bases de données traditionnels. C'est pour répondre à ces différentes problématiques que sont nées les bases de données NoSQL (Not Only SQL), sous l'impulsion de grands acteurs du Web comme Facebook ou Google, qui les avaient développées à l'origine pour leurs besoins propres. Grâce à leur flexibilité et leur souplesse, ces bases non relationnelles permettent en effet de gérer de gros volumes de données hétérogènes sur un ensemble de serveurs de stockage distribués, avec une capacité de montée en charge très élevée. Elles peuvent aussi fournir des accès de paires clé-valeur en mémoire avec une très grande célérité. Réservées jusqu'à peu à une minorité, elles tendent aujourd'hui à se poser en complément du modèle relationnel qui dominait le marché depuis plus de 30 ans. Du choix de la base NoSQL à sa mise en oeuvre Cet ouvrage d'une grande clarté dresse un panorama complet des bases de données NoSQL, en analysant en toute objectivité leurs avantages et inconvénients. Dans une première partie, il présente les grands principes de ces bases non relationnelles : interface avec le code client, architecture distribuée, paradigme MapReduce, etc. Il détaille ensuite dans une deuxième partie les principales solutions existantes (les solutions de Big Data autour de Hadoop, MongoDB, Cassandra, Couchbase Server...), en précisant spécificités, forces et faiblesses de chacune. Complétée par une étude de cas réel, la dernière partie du livre est consacrée au déploiement concret de ces bases : dans quel cas passer au NoSQL ? quelle base adopter selon ses besoins ? quelles données basculer en NoSQL ? comment mettre en place une telle base ? comment la maintenir et superviser ses performances ? À qui s'adresse cet ouvrage ? Aux experts en bases de données, architectes logiciels, développeurs... Aux chefs de projet qui s'interrogent sur le passage au NoSQL
