Que signifient les donn\u00e9es non structur\u00e9es ?<\/span><\/h2>\n

Les donn\u00e9es non structur\u00e9es sont des informations num\u00e9riques qui ne peuvent pas \u00eatre stock\u00e9es efficacement dans une base de donn\u00e9es relationnelle (SGBDR) parce qu’elles n’utilisent pas de mod\u00e8les de donn\u00e9es ou de sch\u00e9mas pr\u00e9d\u00e9finis.<\/p>\n

Les donn\u00e9es non structur\u00e9es, qui peuvent \u00eatre brutes, sont souvent stock\u00e9es dans un lac de donn\u00e9es. Les sources de donn\u00e9es non structur\u00e9es comprennent les capteurs et les actionneurs, les courriels et les messages textuels, les documents Word, les pr\u00e9sentations PowerPoint, les dossiers m\u00e9dicaux \u00e9lectroniques (DME), les images num\u00e9riques, les fichiers audio et les vid\u00e9os.<\/p>\n

Dans les entreprises centr\u00e9es sur le client, les donn\u00e9es non structur\u00e9es peuvent \u00eatre analys\u00e9es pour am\u00e9liorer le marketing relationnel et la gestion de la relation client (CRM).<\/p>\n

Techopedia explique les donn\u00e9es non structur\u00e9es<\/span><\/h2>\n

Les donn\u00e9es non structur\u00e9es sont des donn\u00e9es qui suivent une forme moins ordonn\u00e9e que des \u00e9l\u00e9ments tels que des pages de tableur, des tableaux de base de donn\u00e9es ou d’autres ensembles de donn\u00e9es lin\u00e9aires ou ordonn\u00e9es. En fait, le terme “ensemble de donn\u00e9es” est utile parce qu’il est associ\u00e9 \u00e0 des donn\u00e9es qui se pr\u00e9sentent sous forme de tableaux nets et accessibles, sans contenu suppl\u00e9mentaire, et qui sont li\u00e9es ou \u00e9tiquet\u00e9es dans une structure sp\u00e9cifique.<\/p>\n

\"\"<\/p>\n

Parmi les autres exemples de donn\u00e9es textuelles non structur\u00e9es, on peut citer les documents Word, les pr\u00e9sentations PowerPoint, les messages instantan\u00e9s, les logiciels de collaboration, les documents, les livres, les messages sur les m\u00e9dias sociaux et les dossiers m\u00e9dicaux. Les donn\u00e9es non textuelles non structur\u00e9es sont g\u00e9n\u00e9ralement cr\u00e9\u00e9es dans des m\u00e9dias, tels que les fichiers audio MP3, les images JPEG et les fichiers vid\u00e9o Flash, etc.<\/p>\n

Les donn\u00e9es non structur\u00e9es n’ont g\u00e9n\u00e9ralement pas de mod\u00e8le de donn\u00e9es pr\u00e9d\u00e9fini et peuvent ne pas correspondre aux tables relationnelles. Les donn\u00e9es non structur\u00e9es sont g\u00e9n\u00e9ralement constitu\u00e9es de texte. Cependant, elles peuvent contenir des chiffres et des dates, ainsi que des faits. Il en r\u00e9sulte des ambigu\u00eft\u00e9s difficiles \u00e0 identifier \u00e0 l’aide de logiciels conventionnels.<\/p>\n

Le stockage d’\u00e9normes volumes de donn\u00e9es non structur\u00e9es g\u00e9n\u00e9r\u00e9es au sein d’une entreprise, s’il est mal g\u00e9r\u00e9, peut entra\u00eener des d\u00e9penses plus \u00e9lev\u00e9es. Les donn\u00e9es contenues dans les documents papier ou dans un format \u00e9lectronique doivent \u00eatre scann\u00e9es pour qu’une application de recherche puisse analyser les id\u00e9es, en fonction des mots utilis\u00e9s dans certains contextes. C’est ce qu’on appelle la recherche d’entreprise ou recherche s\u00e9mantique.<\/p>\n","protected":false},"excerpt":{"rendered":"
