Il modello ER permette di capire la struttura delle tabelle che compongono gli strumenti di openDCN.

Nota:
in ogni schema vengono riportate solo le chiavi primarie e gli attributi più utili nell'identificare le relazioni tra le entità.
Di seguito al modello verranno riportati i codici SQL utilizzati per creare le tabelle all'interno del database del sistema.

Le entità evidenziate in azzurro sono quelle principali/fondamentali; quelle evidenziate in verde (con il doppio bordo) rappresentano i sottoinsiemi degli strumenti agenda, meeting, consultazione certificata, discussione informata e delle risorse.
Infine la tabella wiki_documents è evidenziata in rosso perchè rappresenta l'insieme delle tabelle ereditate dal sistema di wiki che gestisce lo stesso.
