Bon cours, dommage qu’on ai pas le temps de tout voir plus en détail.Malheureusement une part importante de la formation ne me concerne pas car plus orienté DBA Applicatif alors que mon rôle est plus orienté infrastructure.

Manque de pratique, notamment sur une base de test, déjà en place ou devons appliquer tout ce qu’on a pu voir, éventuellement accompagné par le présentateur.A l’issue de la formation, nous avons donc une trousse à outils, mais avec très peu de mise en pratique.
