Description du domaine
Le sujet est un lecteur multimédia similaire à iTunes. Les principales entités de cette base de données sont l'utilisateur et la collection de compositions.
Chaque chanson appartient à un seul artiste et à un seul album, mais de nombreux utilisateurs peuvent les ajouter. Chaque utilisateur peut ajouter un nombre illimité de chansons.
Chaque utilisateur doit disposer d'un mail et d'un mot de passe uniques qui peuvent être répétés, grâce à ces informations, l'utilisateur peut se connecter à son compte. De plus, les champs suivants sont obligatoires pour les utilisateurs lors de l'inscription: nom, numéro de téléphone, pays de résidence, date de début d'abonnement et date de fin d'abonnement. Après une connexion correcte ou une inscription réussie, l'utilisateur est dirigé vers la page principale, où l'utilisateur est présenté avec une sélection de morceaux de différents artistes, parmi lesquels il peut choisir ceux qu'il aime et les ajouter à sa playlist. Le nombre de pistes ajoutées n'est pas limité. Chaque utilisateur a son propre compte personnel, dans lequel il peut voir la musique ajoutée, la supprimer, et il existe également une option pour afficher les données personnelles de l'utilisateur saisies par lui lors de son inscription.L'utilisateur peut à tout moment supprimer son compte ainsi que tout son contenu et ses données du système.
Construire un modèle logique
En utilisant la description du domaine, nous avons construit un modèle logique
Remarque
-- «USERS» «TRACK LIST» «SUBSCRIPTION VALIDITY», .
.
.
Construire un modèle relationnel
Le modèle logique a été converti en modèle relationnel à l'aide d'Oracle SQL Developer Data Modeler
Conformité aux formes normales
Toutes les tables de ce modèle correspondent à 1NF, car tous les attributs n'ont qu'une seule valeur pour chaque enregistrement, ce qui exclut la multiplicité.
Toutes les tables sont dans la deuxième forme normale, puisque chaque attribut non clé dépend de manière irréductible d'une clé primaire.
Toutes les tables sont sous la troisième forme normale, car chaque attribut non clé dépend de manière non transitoire de la clé primaire. Il n'y a aucune dépendance d'un attribut non clé à un autre attribut non clé.
Toutes les tables correspondent à NFBC, car les déterminants de toutes les dépendances fonctionnelles sont des clés potentielles.
Explication des dépendances fonctionnelles
Création de bases de données et d'applications
La base de données est créée sur le serveur phpMyAdmin local. Le résultat du programme est présenté ci-dessous:

Tester le programme
Test de la réaction de l'application aux entrées attendues et test de la santé des boutons
Vérifions l'exactitude de la réaction de l'application aux données d'entrée attendues + l'opérabilité de tous les champs, boutons et listes déroulantes.
Vérification de l'exactitude de l'enregistrement des utilisateurs
Vérifiez que le bouton Ajouter de la musique à la bibliothèque utilisateur fonctionne correctement
«FALSE ALARM by THE WEEKND»
«FALSE ALARM by THE WEEKND»
«FALSE ALARM by THE WEEKND» «TRACK LIST» 32
«MY MUSIC», 32
«FALSE ALARM by THE WEEKND»
«FALSE ALARM by THE WEEKND» «TRACK LIST» 32
«MY MUSIC», 32
Vérifier si le bouton pour supprimer la musique de la bibliothèque de l'utilisateur fonctionne correctement

«FALSE ALARM by THE WEEKND»
«MY MUSIC», 32

Vérification du bon fonctionnement du bouton de suppression d'un compte utilisateur du système
«ivanivanov@mail.ru»
«Delete user from system»
«USERS», 18
«Delete user from system»

Test de la réponse de l'application à une entrée erronée
Lors de la saisie de données incorrectes, le programme en informe l'utilisateur
Erreur de saisie de nom incorrecte
Erreur de saisie d'e-mail non valide
Erreur de saisie de numéro de téléphone incorrect
Une erreur qui se produit lors de la tentative de duplication des informations d'identification d'un utilisateur existant
Une erreur qui se produit lors de la tentative de saisie des informations d'identification d'un utilisateur inexistant
Tout fonctionne pour la saisie de données attendue. Pour l'absence d'entrée et pour une entrée incorrecte, le programme émet un avertissement
