Connecting to Database

Hello

At the present time I am using Perl, cgi, Apache Web Page, SQL, and
SYBASE database on a unix server(SUN Fire V 880). I have no problem
accessing the Sybase database, fetching records and display them on the
web page.

My Available Database Drivers are.
DBM
ExampleP
File
Proxy
Sponge
Sybase

Now, I would like to connect to another database on a Microsoft SQL
Server, using Perl from my unix server.

What do I need?

Where can I get information? (book or web page)

Thanks

Oscar
