Vous ouvrez souvent des fichiers Excel ou CSV... et vous les subissez plus que vous ne les comprenez ?
Avec Les bases du SQL - De débutant à pro des jeux de données, découvrez comment parler à vos données sans jargon ni prise de tête.
Ce livre vous guide pas à pas, avec un ton simple et concret, pour:
comprendre ce qu'est vraiment une base de données (tables, lignes, colonnes, clés);
écrire vos premières requêtes: SELECT, WHERE, ORDER BY, LIMIT;
résumer vos données avec COUNT, SUM, AVG, MIN, MAX et GROUP BY;
relier plusieurs tables grâce aux jointures sans vous perdre;
ajouter, modifier ou supprimer des données sans tout casser (INSERT, UPDATE, DELETE, transactions);
prendre de bonnes habitudes: mise en forme des requêtes, gestion des erreurs, tests étape par étape;
transformer vos fichiers de ventes, bases films/clients ou tableaux Excel en mini-projets SQL concrets.
Pensé pour les débutants, les reconversions et les profils non techniques, ce livre se lit par petits blocs de 15-20 minutes et privilégie les exemples du quotidien plutôt que la théorie sèche.
À la fin, vous ne serez peut-être pas guru de la data, mais vous aurez acquis bien plus précieux: le réflexe de poser des questions en SQL dès que vous voyez des données, au travail comme dans vos projets perso.
