Multiple data sources

Hi Guys,
I uses the editor for a mysql database and I understand that process. I am hoping to pull in a mssql data using freetds (already set up and working) It doesn't need to utilize the editor functionality just read only. Whats the best way to do that? Do i create two folders one of editor and one of datatables and reference them separately in my PHP? I guess the question is what best practice to pull from two database types when Mysql is editor and MSSQL is just read only. Thanks for any tips.
