For example - if you have 3 different installations of an ap with three
different user databases and you wanted to build a single interface for all
three (like a master administrators db) - you could create a user on the MS
SQL server with permissions to all three. Then, using a DSN with that USER
You could then run a query like this:
<cfquery name="user" datasource="#application.admindsn#">
SELECT A.username, A.password, 'DB_A' as Datasource
FROM DbnameA.dbo.Users
UNION
SELECT B.username, B.password, 'DB_B' as Datasource
FROM DbnameB.dbo.Users
UNION
SELECT C.username, C.password, 'DBC' as Datasource
FROM DbnameC.dbo.Users
order by Datasource
</cfquery>
This would give you all the users from all three databases
It is also possible to do similar things in Access by specifying the file
path to the second datasource.... I had a sample of that once but its fallen
by the wayside.
Obviously there is a security issue here - 1 username with permissions on 3
databases... so make sure you have thought it all through.

Yep basically the format is database.owner.table.column
So you could do SELLECT * FROM EmployeeDirectory.dbo.Employee

If you use MS SQL you can use Linked Servers to query across different
servers. it would be something like:
Select *
>From myLink.database.owner.table
