Assistance with S&P Xpressfeed Database

I need assistance creating an in-house SQL Database that relies on extracting data from the Standard and Poors Xpressfeed database. I am looking to extract 80 items from the all the historical financial statements of selected companies, and the pricing history (both daily and monthly). The key to this project is knowledge of Xpressfeed. If you have used the dataset in the past and understand how the tables and keys fit together, I would be very interested in hearing from you.
