Cet article présente principalement la méthode d'implémentation de la fonction de statistiques de données dans le système d'information de gestion Asp.net. Les amis qui en ont besoin peuvent s'y référer
Les statistiques de données sont une fonction essentielle dans tout système. dirigeants Très utile pour rapporter les statistiques et les données de progression nécessaires au travail.
À mon avis, un module statistique devrait mettre en œuvre les fonctions suivantes :
Être capable d'afficher les résultats statistiques des requêtes couramment utilisées ;
Les résultats affichés peuvent être sous forme de tableau ou sous forme graphique. S'ils sont graphiques, ils peuvent être affichés sous plusieurs formes (histogramme, diagramme linéaire, diagramme circulaire, diagramme radar, diagramme à barres empilées, etc.) :
Résultats de requêtes statistiques, cliquez sur des chiffres ou des pourcentages pour afficher des données détaillées
Vous pouvez librement combiner des conditions de requête, des conditions de filtrage, des conditions de regroupement ; , et le tri, etc. ;
Il est préférable d'avoir un aperçu en temps réel des résultats statistiques
Les statistiques des requêtes peuvent être enregistrées afin que les requêtes statistiques peuvent être directement appelées et affichées la prochaine fois. Les résultats
Pour les statistiques de requête enregistrées, les résultats de la requête peuvent également être filtrés selon la méthode de filtrage flexible la prochaine fois ; appelé ;
L'interface doit être simple et intuitive, pour que même les opérateurs qui ne connaissent pas grand-chose en informatique puissent l'utiliser facilement
