being new to the Sharepoint scene, I was wondering what the best approach was in this situation.

I have a few customers, who all login into the Main Home site, and then get a link to their resp. Subsite according to their Company Name.

I was wondering what kind of approach I should take to let the subsite have a page which displays the table, filtered with a WHERE companyName = 'nameOfCompany'-clause.

Can anyone give me some information on this? I should use a Webpart for this?

Regards
