Updating/importing? Question

Hello all, I have a question;
I have 2 databases with 4 tables in it following the same structure.
Table 1: tblPersons consisting employeenumber as pk
Table 2: tblLocation consisting the location as pk
Table 3: tblCompanyvehicle consisting the licenseplate as pk
Table 4: tblAssets consisting serialnumber as pk
All tables have relationships build on the employeenumber which is a pulldown in the three last tables.
I have a thirdth empty exact same database and want to import the tables from the 2 other databases by clicking a button, browse to the database and click import.
The import should IGNORE duplicates without a message (if New York already excists there is no reason to insert it again, the same goes for employeenumbers, since they are unique, etc, etc).
Is there any way to do this?
Thanks in advance

(I did a search on this, but nothing came up that described the problem)
