Yes, but I have to give a special serial number for all equipments for each customer. So that equipments is the same. For example ; George has takes a broom, bucket and brush. Michael has takes the same a broom, bucket and brush. File is the same equipment and this database also has a repeating files.I want to give repeating files database a different numbers as a referance by the other file. Thanks a lot.

You'll need at least 4 tables:

Customers

Equipments

Orders

Order Line Items

The autoentered ID of the last table meets your needs.
