Question about connecting one database to another

I have the standard Microsoft SBS 2003 SharePoint services runing.

I have create a standard website for the company to use for information.

I am trying to create something I believe is suppose to work, but I can't
seem to get it to work.

From the Home page, I have created a LIST called SERVER UPDATES. This list
is for the administrator's use only. The Administrator will post
modifications to this for his use to keep track of changes he/and others,
have made. Software installs, version upgrades, service packs etc.

I want the users to be able to see these updates (only certain rows that
pertain to them), so I created an ANNOUNCEMENT list.

In that announcement list, I added a column, and told it it was information
from another part of this site. When I do that, I only have two selections,
ID and TITLE.

I thought there was a way to say, all the columns under a certain "site" you
could import into another site?

Thanks
