related to Database planning

Hello All

I am developing a site which will take data from our members. This data will first go to the administrator through VB application.
After validation of this data administrator will send this data to final database, Which will used in our site.

Now I want to perpare database for above.

can u suggest me the best practical method to design database for this type of site.

I think I have to prepare 2 database with same table in it.
1) when the data is inputed from site by our
member.
2) Database for the data which is transfered by
administrator, Which will be used in site for
final user.
we use SQL as backhand.

thanks
