InfoPath Dev

I have 12 Front end's that use a common access database with linked tables etc. Easily over 200 forms. I was wondering what coding considerations I should go over before moving some of the forms to Infopath? Thanks in advance.

I want to pull all the data from a query and have it displayed on an Infopath form. I dont need to modify the data in any means(nor would it be possible given the amount of joins xD). I have created a form using MS Access Connection and can see Q and D field data in the Data Source window. Where do I go from here?
