I despise this sort of notation, and have instead adopted what have cheerfully named Hungarian Suffix notation, the reason being Signal-To-Noise ratio. Instead of prefacing everything with some form of prefix, just do the opposite:
Customer_tbl Customer_Dead_boo Customer_DOB_date Customer_qs (that means Query Select) Customer_qu (that means Query Update) Customer_qd (that means Query Delete) CustomerOrders_tbl Customer_frm (a form that opens the Customer table; could involve subforms, but in that case they are named Customer_Orders_fsub, Customer_Payments_fsub, and so on. Easy to read, obvious the intent, and easily sortable. Just my opinion. Arthur
