What separate record of one domain to another domain?

Hi,

I have a problem.

On the one domain www.domain1.com save employees
in another domain www.domain2.com save other employees.


What is the best solution for this?

Do I need to save each table id_domain?

Example:
Table: tbl_domainname
ID, domainname
1, www.domain1.com
2, www.domain2.com


Then, in each table ID_domene I save?
tbl_employees:
ID, ID_domain, firstname
1 1 firstname1
2 1 firstname2
3 2 firstname1000

Is there any better way to do this?
 
Regards,
Dejan
