Bonsoir tous le monde

dans mon application web j'ai 2 tables:
bc(id_bc,date_bc)
operation(id_operation,operation)
liés n-n qui me donne en résultat 3 tables:
bc(id_bc,date_bc)
operation(id_operation,operation)
bc_operation(id_bc,id_operation)

avec une base données oracle
les classe sont générées :
