Essai de la mise en place d'une plate- forme informatique Direction Générale des Impôts opérateur économique "déclaration électronique " en RDC

5.5.8. FORMULAIRE DECLARATIF « DECLARATION ELECTRONIQUE  »

Le formulaire offre une manière conviviale de saisir les données. Il minimise les erreurs de saisie par sa grande ressemblance avec un document papier, et comporte des champs provenant de plusieurs tables, ce qui nous évite de passer d'une table à l'autre lors de l'entrée des données^10(*).

Par des tables, des requêtes et des formulaires, nous exploitons au mieux nos bases de données en uniformisant et en simplifiant la saisie des données.

Le formulaire proposé est élaboré avec les Assistants formulaires instantanés et nous avons continué à le personnaliser en Mode création.

Deux requêtes furent crées à partir des certaines tables.

- Requête Contribuable (table Adresse et table Contribuable)

- Requête Déclaration (table déclaration et table impôt)
