Hi All,

i have one double currently we used embedded object like :

employee table
empid

loantable
loanid


jointable
empi loanid

in join table i did not use primary key for entity class . so we used total there four classes

employee class{
Set<Loads> loans=new HashSet<Load>();
}
Loan class{

}
JoinTable class{

JoinTableId id;

}

JoinTableId class{

Employee employee;
Loan loan
}


if we use primary key for jointable uses only three classes

JoinTable{
long primarykey;
Employee emp;
Loan loan;
}

my double is which is better approach could you please suggest me ?


Thanks
Naresh
