DataGridView with multiple tables[Show/Insert/Update/Delete]

Question

Hello,

I'm using VS2008 [C#]

DB - Oracle11G

I have a database with two tables.Namely Emp_Master and Emp_Details.

How to show these two table[some columns] data in the datagridview and 

insert/update/delete should be affected in both tables Emp_Master and Emp_Details.

Could someone tell me how to code this?

Thanks in advance.
