Come creare schema E-R in mysql

Question

Sto usando MySQL. Ci sono 28 tabelle nel mio database. Ho cercato di usare MySQL Workbench per creare diagramma di E-R. Come ci sono 28 tavoli, tutto è incasinato nel diagramma utilizzando MySQL Workbench. Esiste un modo per creare E-R Schema che mostra tutti i rapporti correttamente tra 28 tavoli ??

Grazie

The only free app I've been able to find that generates decent graphics (not beautiful but quite clear) is SchemaSpy. It's a command line Java program that generates quite comprehensive HTML documentation for any DBMS.
